+Server Requirements
+-------------------
+
+* PHP version 5.6 to 7.2 is recommended. Please note that PHP needs to have `php-gd`, `php-bcmath`, `php-intl`, `php-openssl`, `php-mbstring` and `php-curl` installed and enabled.
+
+* MySQL 5.5, 5.6 and 5.7 are supported, also MariaDB replacement is supported and apparently offering better performance.
+
+* Apache 2.2 and 2.4 are supported. Also Nginx has been proven to work fine, see [wiki page here](https://github.com/opensourcepos/opensourcepos/wiki/Local-Deployment-using-LEMP)
+
+* Raspberry PI based installations proved to work, see [wiki page here](https://github.com/opensourcepos/opensourcepos/wiki/Installing-on-Raspberry-PI---Orange-PI-(Headless-OSPOS))
+
+* For Windows based installations please read [the wiki](https://github.com/opensourcepos/opensourcepos/wiki) and also existing closed issues as this topic has been covered well in all the variants and issues.
+
+
+Local install
+-------------
+
+First of all, if you're seeing the message **'system folder missing'** after launching your browser, then that means you have cloned the repository and have not built the project properly.
+
+1. Dowload the latest [stable release](https://github.com/opensourcepos/opensourcepos/releases) from github or [unstable build](https://bintray.com/jekkos/opensourcepos/opensourcepos/view/files?sort=updated&order=asc#files) from bintray. A regular repository clone will not work unless you are brave enough to build the whole project!
+2. Create/locate a new mysql database to install open source point of sale into
+3. Execute the file database/database.sql to create the tables needed
+4. unzip and upload Open Source Point of Sale files to web server
+5. Modify application/config/database.php and modify credentials if needed to connect to your database
+6. Modify application/config/config.php encryption key with your own
+7. Go to your point of sale install public dir via the browser
+8. LOGIN using
+  * username: admin 
+  * password: pointofsale
+9. Enjoy
+10. Oops an issue? Please make sure you read the FAQ, wiki page and you checked open and closed issue on GitHub. PHP display_errors is disabled by default. Create an application/config/.env file from the .env.example to enable it in a development environment. 
+
+
+Local install using Docker
+--------------------------
+
+From now on ospos can be deployed using Docker on Linux, Mac or Windows. This setup dramatically reduces the number of possible issues as all setup is now done in a Dockerfile. Docker runs natively on mac and linux, but will require more overhead on windows. Please refer to the docker documentation for instructions on how to set it up on your platform.
+
+* To build and run the image, download the latest build from bintray and issue following commands in a terminal with docker installed
+
+```
+    docker-compose build
+    docker-compose up 
+```
+
+* If you want to run from the latest git source, then use docker and composer to run the build
+
+```
+  docker run --rm -v $(pwd):/app composer/composer install
+  docker run --rm -v $(pwd):/app -w /app lucor/php7-cli php bin/install.php translations develop
+  docker run --rm -it -v $(pwd):/app -w /app digitallyseamless/nodejs-bower-grunt "sh -c npm install && bower install"
+  docker-compose build
+  docker-compose up
+```
+
+Cloud install
+-------------
+
+A quick option would be to install directly to [Digitalocean](https://m.do.co/c/ac38c262507b) using their preconfigured LAMP stack. 
+Create a DO account first, add a droplet with preconfigured LAMP and follow the instructions for Local Install below. You will be running a provisioned VPS within minutes.
+
+
+Cloud install using Docker 
+--------------------------
+This installation is NOT Recommended anymore and will soon be replaced by a one click DO installation procedure.
+Existing setups will keep working until the 21th of May but will need to be migrated in time in order to ensure user's safety.
+
+
+If you want to run a quick demo of ospos or run it permanently in the cloud, then we
+suggest using Docker cloud together with the DigitalOcean hosting platform. This way all the
+configuration is done automatically and the install will just work. 
+
+If you choose *DigitalOcean* [through this link](https://m.do.co/c/ac38c262507b), you will get a *$10 credit* for a first
+month of uptime on the platform. A full setup will only take about 2 minutes by following steps below.
+
+1. Create a [Digitalocean account](https://m.do.co/c/ac38c262507b)
+2. Create a [docker cloud account](https://cloud.docker.com)
+3. Login to docker cloud
+4. Associate your docker cloud account with your previously created digital ocean account under settings
+5. Create a new node on DigitalOcean through the `Infrastructure > Nodes` tab. Fill in a name (ospos) and choose a region near to you. We recommend to choose a node with minimum 1G RAM for the whole stack
+6. Click [![Deploy to Docker Cloud](https://files.cloud.docker.com/images/deploy-to-dockercloud.svg)](https://cloud.docker.com/stack/deploy/?repo=https://github.com/opensourcepos/opensourcepos) 
+7. Othewise create a new stack under `Applications > Stacks` and paste the [contents of docker-cloud.yml](https://github.com/opensourcepos/opensourcepos/blob/master/docker-cloud.yml) from the source repository in the text field and hit `Create and deploy` 
+8. Find your website url under `Infrastructure > Nodes > <yournode> > Endpoints > web`
+9. Login with default username/password admin/pointofsale
+10. DNS name for this server can be easily configured in the DigitalOcean control panel
+
+More info [on maintaining a docker](https://github.com/opensourcepos/opensourcepos/wiki/Docker-cloud-maintenance) install can be found on the wiki

+Introduction
+------------
 
-A more extensive setup guide can be found at [this site](http://www.opensourceposguide.com/guide/gettingstarted/installation)
+Open Source Point of Sale is a web based point of sale system.
+The main features are:
+* Stock management (Items and Kits)
+* VAT, customer and multi tiers taxation
+* Sale register with transactions logging
+* Quotation and invoicing
+* Expenses logging
+* Receipt and invoice printing and/or emailing
+* Barcode generation and printing
+* Suppliers and Customers database
+* Multiuser with permission control
+* Reporting on sales, orders, expenses, inventory status
+* Receivings
+* Giftcard
+* Rewards
+* Restaurant tables
+* Messaging (SMS)
+* Multilanguage
+* Selectable Boostrap (Bootswatch) based UI theme
+* Mailchimp integration
+* reCAPTCHA to protect login page from brute force attacks
 
-If you like the project, and you are making money out of it on a daily basis, then consider to buy me a coffee so I can keep adding features.
+The software is written in PHP language, it uses MySQL (or MariaDB) as data storage back-end and has a simple but intuitive user interface.
 
+The latest 3.x version is a complete overhaul of the original software.
+It is now based on Bootstrap 3 using Bootswatch themes, and still uses CodeIgniter 3 as framework.
+It also has improved functionality and security.
+
+Deployed to a Cloud it's a SaaS (Software as a Service) solution.
+
+
+Installation
+------------

+FAQ
+---
+
+* If you are seeing the message **system folder missing**, then you have cloned the source using git and you need to run a build *first*. Check [INSTALL.md](https://github.com/opensourcepos/opensourcepos/blob/master/INSTALL.md) for instructions or download latest zip file from [bintray](https://bintray.com/jekkos/opensourcepos/opensourcepos/view/files?sort=updated&order=desc#files) instead.
+
+* If at login time you read "The installation is not correct, check your php.ini file.", please check the error_log in public folder to understand what's wrong and make sure you read the [INSTALL.md](https://github.com/opensourcepos/opensourcepos/blob/master/INSTALL.md).
+
+* If you installed your OSPOS under a web server subdir, please edit public/.htaccess and go to the lines with comment `if in web root` and `if in subdir comment above line, uncomment below one and replace <OSPOS path> with your path` and follow the instruction on the second comment line. If you face more issues please read [issue #920](https://github.com/opensourcepos/opensourcepos/issues/920) for more help.
+
+* Apache server configurations are SysAdmin issues and not strictly related to OSPOS. Please make sure you first can show a "hello world" html page before pointing to OSPOS public directory. Make sure .htaccess is correctly configured.
+
+* If the avatar pictures are not shown in Items or at Item save time you get an error, please make sure your public and subdirs are assigned to the correct owner and the access permission is set to 755.
+
+* If you install ospos in docker behind a proxy that performs ssloffloading, you can enable the url generated to be https instead of http, by activating the environment variable FORCE_HTTPS = 1.
+
+* If you have suhosin installed and face an issue with CSRF, please make sure you read [issue #1492](https://github.com/opensourcepos/opensourcepos/issues/1492).

 How to Upgrade
 -------------------------
-1. Replace all code from your point of sale installation with the code downloaded
-2. Run the necessary database upgrades from the database folder
+1. Backup all your current database and OSPOS code
+2. Make sure you have a copy of application/config/config.php and application/config/database.php
+3. Remove all directories
+4. Install the new OSPOS
+5. Run the database upgrade scripts from database/ dir (check which ones you need according to the version you are upgrading from and only applicable if upgrading from pre 3.0.0)
+6. Take the saved old config.php and upgrade the new config.php with any additional changes you made in the old.
+   Take time to understand if new config rules require some changes (e.g. encryption keys)
+7. Take the saved old database.php and change the new database.php to contain all the configuration you had in the old setup.
+   Please try not to use the old layout, use the new one and just copy the content of the config variables
+8. Restore the content of the old uploads/ folder into public/uploads/ one
+9. Once the new code is in place, database is updated and config files are sorted you are good to start the new OSPOS
+10. The first login will take longer because OSPOS post 3.0.0 will upgrade automatically to the latest version
+11. Now you can use OSPOS
+12. If any issue please check README, FAQ and GitHub issues as somebody else might have had your problem already before creating a new issue

+| page of the User Guide.
+|
+| -------------------------------------------------------------------
+| EXPLANATION OF VARIABLES
+| -------------------------------------------------------------------
+|
+|	['dsn']      The full DSN string describe a connection to the database.
+|	['hostname'] The hostname of your database server.
+|	['username'] The username used to connect to the database
+|	['password'] The password used to connect to the database
+|	['database'] The name of the database you want to connect to
+|	['dbdriver'] The database driver. e.g.: mysqli.
+|			Currently supported:
+|				 cubrid, ibase, mssql, mysql, mysqli, oci8,
+|				 odbc, pdo, postgre, sqlite, sqlite3, sqlsrv
+|	['dbprefix'] You can add an optional prefix, which will be added
+|				 to the table name when using the  Query Builder class
+|	['pconnect'] TRUE/FALSE - Whether to use a persistent connection
+|	['db_debug'] TRUE/FALSE - Whether database errors should be displayed.
+|	['cache_on'] TRUE/FALSE - Enables/disables query caching
+|	['cachedir'] The path to the folder where cache files should be stored
+|	['char_set'] The character set used in communicating with the database
+|	['dbcollat'] The character collation used in communicating with the database
+|				 NOTE: For MySQL and MySQLi databases, this setting is only used
+| 				 as a backup if your server is running PHP < 5.2.3 or MySQL < 5.0.7
+|				 (and in table creation queries made with DB Forge).
+| 				 There is an incompatibility in PHP with mysql_real_escape_string() which
+| 				 can make your site vulnerable to SQL injection if you are using a
+| 				 multi-byte character set and are running versions lower than these.
+| 				 Sites using Latin-1 or UTF-8 database character set and collation are unaffected.
+|	['swap_pre'] A default table prefix that should be swapped with the dbprefix
+|	['encrypt']  Whether or not to use an encrypted connection.
+|
+|			'mysql' (deprecated), 'sqlsrv' and 'pdo/sqlsrv' drivers accept TRUE/FALSE
+|			'mysqli' and 'pdo/mysql' drivers accept an array with the following options:
+|
+|				'ssl_key'    - Path to the private key file
+|				'ssl_cert'   - Path to the public key certificate file
+|				'ssl_ca'     - Path to the certificate authority file
+|				'ssl_capath' - Path to a directory containing trusted CA certificats in PEM format
+|				'ssl_cipher' - List of *allowed* ciphers to be used for the encryption, separated by colons (':')
+|				'ssl_verify' - TRUE/FALSE; Whether verify the server certificate or not ('mysqli' only)
+|
+|	['compress'] Whether or not to use client compression (MySQL only)
+|	['stricton'] TRUE/FALSE - forces 'Strict Mode' connections
+|							- good for ensuring strict SQL while developing
+|	['ssl_options']	Used to set various SSL options that can be used when making SSL connections.
+|	['failover'] array - A array with 0 or more data for connections if the main should fail.
+|	['save_queries'] TRUE/FALSE - Whether to "save" all executed queries.
+| 				NOTE: Disabling this will also effectively disable both
+| 				$this->db->last_query() and profiling of DB queries.
+| 				When you run a query, with this setting set to TRUE (default),
+| 				CodeIgniter will store the SQL statement for debugging purposes.
+| 				However, this may cause high memory usage, especially if you run
+| 				a lot of SQL queries ... disable this to avoid that problem.
+|
+| The $active_group variable lets you choose which connection group to
+| make active.  By default there is only one group (the 'default' group).
+|
+| The $query_builder variables lets you determine whether or not to load
+| the query builder class.

-# How to contribute
-
-- [Getting help](#getting-help)
-- [Submitting bug reports](#submitting-bug-reports)
-- [Contributing code](#contributing-code)
-
-## Getting help
-
-Community discussion, questions, and informal bug reporting is done on the
-[dompdf Google group](http://groups.google.com/group/dompdf). You may also 
-seek help on
-[StackOverflow](http://stackoverflow.com/questions/tagged/dompdf).
-
-## Submitting bug reports
-
-The preferred way to report bugs is to use the
-[GitHub issue tracker](http://github.com/dompdf/dompdf/issues). Before 
-reporting a bug, read these pointers.
-
-**Please search inside the bug tracker to see if the bug you found is not already reported.**
-
-**Note:** The issue tracker is for *bugs* and *feature requests*, not requests for help.
-Questions should be asked on the
-[dompdf Google group](http://groups.google.com/group/dompdf) instead.
-
-### Reporting bugs effectively
-
-- dompdf is maintained by volunteers. They don't owe you anything, so be
-  polite. Reports with an indignant or belligerent tone tend to be moved to the
-  bottom of the pile.
-
-- Include information about **the PHP version on which the problem occurred**. Even
-  if you tested several PHP version on different servers, and the problem occurred
-  in all of them, mention this fact in the bug report.
-  Also include the operating system it's installed on. PHP configuration can also help,
-  and server error logs (like Apache logs)
-
-- Mention which release of dompdf you're using (the zip, the master branch, etc).
-  Preferably, try also with the current development snapshot, to ensure the
-  problem has not already been fixed.
-
-- Mention very precisely what went wrong. "X is broken" is not a good bug
-  report. What did you expect to happen? What happened instead? Describe the
-  exact steps a maintainer has to take to make the problem occur. We can not
-  fix something that we can not observe.
-
-- If the problem can not be reproduced in any of the demos included in the
-  dompdf distribution, please provide an HTML document that demonstrates
-  the problem. There are a few options to show us your code:
-   - [JS Fiddle](http://jsfiddle.net/)
-   - [dompdf debug helper](http://eclecticgeek.com/dompdf/debug.php) (provided by @bsweeney)
-   - Include the HTML/CSS inside the bug report, with
-   [code highlighting](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#wiki-code).
-
-## Contributing code
-
-- Make sure you have a [GitHub Account](https://github.com/signup/free)
-- Fork [dompdf](https://github.com/dompdf/dompdf/)
-  ([how to fork a repo](https://help.github.com/articles/fork-a-repo))
-- *Make your changes on the dev branch* or the most appropriate feature branch. Please only patch 
-  the master branch if you are attempting to address an urgent bug in the released code.
-- Add a simple test file in `www/test/`, with a comprehensive name.
-- Submit a pull request
-([how to create a pull request](https://help.github.com/articles/fork-a-repo))

-### Coding standards
-
-- 2 spaces per indentation level, no tabs.
-- spaces inside `if` like this:
-```php

-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.

-**dompdf is an HTML to PDF converter**.
-At its heart, dompdf is (mostly) [CSS 2.1](http://www.w3.org/TR/CSS2/) compliant
-HTML layout and rendering engine written in PHP. It is a style-driven renderer:
-it will download and read external stylesheets, inline style tags, and the style
-attributes of individual HTML elements. It also supports most presentational
-HTML attributes.
-
-----
-
-**Check out the [Demo](http://pxd.me/dompdf/www/examples.php) and ask any
-question on [StackOverflow](http://stackoverflow.com/questions/tagged/dompdf) or
-on the [Google Groups](http://groups.google.com/group/dompdf)**

-
-Features
-========
- * handles most CSS 2.1 and a few CSS3 properties, including @import, @media &
-   @page rules
- * supports most presentational HTML 4.0 attributes
- * supports external stylesheets, either local or through http/ftp (via
-   fopen-wrappers)
- * supports complex tables, including row & column spans, separate & collapsed
-   border models, individual cell styling
- * image support (gif, png (8, 24 and 32 bit with alpha channel), bmp & jpeg)
- * no dependencies on external PDF libraries, thanks to the R&OS PDF class
- * inline PHP support
- 
-Requirements
-============
- * PHP 5.0+ (5.3+ recommended)
- * DOM extension
- * GD extension
-
-Recommendations
-============
- * MBString extension: provides internationalization support. This extension is
-   *not* enabled by default. dompdf has limited internationalization support
-   when this extension is not enabled.
- * opcache (OPcache, XCache, APC, etc.): improves performance
-
-About Fonts & Character Encoding
-============
-PDF documents internally support the following fonts: Helvetica, Times-Roman,
-Courier, Zapf-Dingbats, & Symbol. These fonts only support Windows ANSI
-encoding. In order for a PDF to display characters that are not available in
-Windows ANSI you must supply an external font. dompdf will embed any referenced
-font in the PDF so long as it has been pre-loaded or is accessible to dompdf and
-reference in CSS @font-face rules. See the
-[font overview](https://github.com/dompdf/dompdf/wiki/About-Fonts-and-Character-Encoding)
-for more information on how to use fonts.
-
-The [DejaVu TrueType fonts](http://dejavu-fonts.org) have been pre-installed to
-give dompdf decent Unicode character coverage by default. To use the DejaVu
-fonts reference the font in your stylesheet, e.g. `body { font-family: Deja Vu
-Sans; }` (for DejaVu Sans).
-
-Easy Installation
-============
-Install with git
----
-From the command line switch to the directory where dompdf will reside and run
-the following commands:
-
-```sh
-git clone https://github.com/dompdf/dompdf.git
-git submodule init
-git submodule update
-```
-
-Install with composer
----
-To install with Composer, simply add the requirement to your `composer.json`
-file:
-
-```json
-{
-  "require" : {
-    "dompdf/dompdf" : "0.6.*"
-  }
-}
-```
-
-And run Composer to update your dependencies:
-
-```bash
-$ curl -sS http://getcomposer.org/installer | php
-$ php composer.phar update
-```
-    
-Before you can use the Composer installation of DOMPDF in your application you
-must disable dompdf's default auto-loader, include the Composer autoloader, and
-load the dompdf configuration file:
-
-```php
-// somewhere early in your project's loading, require the Composer autoloader
-// see: http://getcomposer.org/doc/00-intro.md
-require 'vendor/autoload.php';
-
-// disable DOMPDF's internal autoloader if you are using Composer
-define('DOMPDF_ENABLE_AUTOLOAD', false);
-
-// include DOMPDF's default configuration
-require_once '/path/to/vendor/dompdf/dompdf/dompdf_config.inc.php';
-```
-
-Download and install
----
-Download an archive of dompdf and extract it into the directory where dompdf
-will reside
- * You can download stable copies of dompdf from
-   https://github.com/dompdf/dompdf/tags
- * Or download a nightly (the latest, unreleased code) from
-   http://eclecticgeek.com/dompdf
-
-Limitations (Known Issues)
-==========================
- * not particularly tolerant to poorly-formed HTML input. To avoid any
-   unexpected rendering issues you should either enable the built-in HTML5
-   parser (via the `DOMPDF_ENABLE_HTML5PARSER` configuration constant) or run
-   your HTML through a HTML validator/cleaner (such as Tidy).
- * large files or large tables can take a while to render
- * CSS float is not supported (but is in the works, enable it through the
-   `DOMPDF_ENABLE_CSS_FLOAT` configuration constant).
- * If you find this project useful, please consider making a donation.
