+# 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))

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ 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.

+
+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.

+   * http://www.w3.org/TR/CSS21/page.html#allowed-page-breaks
+   * 
+   * In the normal flow, page breaks can occur at the following places:
+   * 
+   *    1. In the vertical margin between block boxes. When a page
+   *    break occurs here, the used values of the relevant
+   *    'margin-top' and 'margin-bottom' properties are set to '0'.
+   *    2. Between line boxes inside a block box.
+   *
+   * These breaks are subject to the following rules:
+   * 
+   *   * Rule A: Breaking at (1) is allowed only if the
+   *     'page-break-after' and 'page-break-before' properties of
+   *     all the elements generating boxes that meet at this margin
+   *     allow it, which is when at least one of them has the value
+   *     'always', 'left', or 'right', or when all of them are
+   *     'auto'.
+   *
+   *   * Rule B: However, if all of them are 'auto' and the
+   *     nearest common ancestor of all the elements has a
+   *     'page-break-inside' value of 'avoid', then breaking here is
+   *     not allowed.
+   *
+   *   * Rule C: Breaking at (2) is allowed only if the number of
+   *     line boxes between the break and the start of the enclosing
+   *     block box is the value of 'orphans' or more, and the number
+   *     of line boxes between the break and the end of the box is
+   *     the value of 'widows' or more.
+   *
+   *   * Rule D: In addition, breaking at (2) is allowed only if
+   *     the 'page-break-inside' property is 'auto'.
+   *
+   * If the above doesn't provide enough break points to keep
+   * content from overflowing the page boxes, then rules B and D are
+   * dropped in order to find additional breakpoints.
+   *
+   * If that still does not lead to sufficient break points, rules A
+   * and C are dropped as well, to find still more break points.
+   *
+   * We will also allow breaks between table rows.  However, when
+   * splitting a table, the table headers should carry over to the
+   * next page (but they don't yet).
