 ----------

 This document assumes you have a little knowledge about software
 compilation. If you experience difficulties with the dependencies or

 Dependencies
 ------------

-The Libkiwix relies on many third party software libraries. They are
-prerequisites to the Libkiwix compilation. Following libraries need to
-be available:
-* [ICU](https://site.icu-project.org/) (package `libicu-dev` on Ubuntu)
-* [ZIM](https://openzim.org/) (package `libzim-dev` on Ubuntu)
-* [Pugixml](https://pugixml.org/) (package `libpugixml-dev` on Ubuntu)
-* [Mustache](https://github.com/kainjow/Mustache) (Just copy the
-header `mustache.hpp` somewhere it can be found by the compiler and/or
-set CPPFLAGS with correct `-I` option). Use Mustache version 4.1 or above.
-* [Libcurl](https://curl.se/libcurl) (`libcurl4-gnutls-dev`, `libcurl4-nss-dev` or `libcurl4-openssl-dev` on Ubuntu)
-* [Microhttpd](https://www.gnu.org/software/libmicrohttpd) (package `libmicrohttpd-dev` on Ubuntu)
-* [Zlib](https://zlib.net/) (package `zlib1g-dev` on Ubuntu)
+The Kiwix library relies on many third parts software libraries. They

+
+Environnement
 -------------

+The Kiwix library builds using [Meson](http://mesonbuild.com/) version
+0.34 or higher. Meson relies itself on Ninja, pkg-config and few other
 compilation tools.

 Install first the few common compilation tools:
-* [Meson](https://mesonbuild.com/)
-* [Ninja](https://ninja-build.org/)
-* [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/)
+* Automake
+* Libtool
+* Virtualenv
+* Pkg-config

-These tools should be packaged if you use a cutting edge operating
-system. If not, have a look to the [Troubleshooting](#Troubleshooting)
-section.
-
-Compilation
-----------
-
-Once all dependencies are installed, you can compile the Libkiwix
-with:
-```bash
-meson . build
-ninja -C build
+Then install Meson itself:
 ```
-
-By default, it will compile dynamic linked libraries. All binary files
-will be created in the `build` directory created automatically by
-Meson. If you want statically linked libraries, you can add
-`--default-library=static` option to the Meson command.
-
-Depending of you system, `ninja` may be called `ninja-build`.
-
-The android wrapper uses deprecated methods of libkiwix so it cannot be compiled
-with `werror=true` (the default). So you must pass `-Dwerror=false` to meson:
-
-```bash
-meson . build -Dwrapper=android -Dwerror=false
-ninja -C build
-```
-
-Static files compilation
------------------------
-
-Libkiwix has a few static files 'compiled' within the binary
-code. This is mostly Javascript/HTML/pictures necessary for the HTTP
-daemon.
-
-These static files are available in the `static` directory and are
-compiled by custom Python code available in this repository `scripts`
-directory. This happens automatically at compilation time without any
-additional command to run.
-
-To avoid HTTP caching issues, the URLs (to the static content) are
-appended with a `cacheid` parameter (this is called "cache
-busting"). This `cacheid` value derived from the
-[sha1sum](https://en.wikipedia.org/wiki/Sha1sum) of each targeted
-static file. As a consequence, each time you change a static file, the
-corresponding `cacheid` value will change.
-
-To properly test this feature, this `cacheid` needs to be added
-manually to the automated tests and has to be commited. After
-modifying the needed static file, [run the automated
-tests](#Testing). They will fail, but the inspection of the testing
-log will give you the new `cacheid` value(s). Finally update
-`test/server.cpp` with the appropriate `cacheid` value(s) which have
-changed.
-
-Testing
-------
-
-To run the automated tests:
-```bash
-cd build
-meson test
-```
-
-Installation
------------
-
-If you want to install the Libkiwix and the headers you just have
-compiled on your system, here we go:
-```bash
-ninja -C build install
-```
-
-You might need to run the command as root (or using `sudo`), depending
-where you want to install the libraries. After the installation
-succeeded, you may need to run `ldconfig` (as `root`).
-
-Uninstallation
--------------
-
-If you want to uninstall the Kiwix library:
-```bash
-ninja -C build uninstall
-```
-
-Like for the installation, you might need to run the command as `root`
-(or using `sudo`).
-
-Custom Index Page
-----------------
-
-to use custom welcome page mention `customIndexPage` argument in `kiwix::internalServer()` or use `kiwix::server->setCustomIndexTemplate()`.
-(note - while using custom html file please mention all external links as absolute path.)
-
-to create a HTML template with custom JS you need to have a look at various OPDS based endpoints as mentioned [here](https://wiki.kiwix.org/wiki/OPDS) to load books.
-
-To use JS provided by kiwix-serve you can use the following template to start with ->
-
-```
-<!DOCTYPE html>
-<html xmlns="http://www.w3.org/1999/xhtml">
-  <head>
-    <meta charset="UTF-8" />
-    <meta name="viewport" content="width=device-width,initial-scale=1" />
-    <title><-- Custom Tittle --></title>
-    <script src="{{root}}/skin/isotope.pkgd.min.js" defer></script>
-    <script src="{{root}}/skin/iso6391To3.js"></script>
-    <script type="text/javascript" src="{{root}}/skin/index.js" defer></script>
-  </head>
-  <body>
-  </body>
-</html>
-```
-
- To get books listed using `index.js` add - `<div class="book__list"></div>` under body tag.
- To get number of books listed add - `<h3 class="kiwixHomeBody__results"></h3>` under body tag.
- To add language select box add - `<select id="languageFilter"></select>` under body tag.
- To add category select box add - `<select id="categoryFilter"></select>` under body tag.
- To add search box for books use following form -
-    ```
-        <form id='kiwixSearchForm'>
-        <input type="text" name="q" placeholder="Search" id="searchFilter" class='kiwixSearch filter'>
-        <input type="submit" class="kiwixButton" value="Search"/>
-        </form>
-    ```
-
-
-If you compile manually Libmicrohttpd, you might need to compile it
-without GNU TLS, a bug here will impeach further compilation
-otherwise.
-
-If the compilation still fails, you might need to get a more recent
-version of a dependency than the one packaged by your Linux
-distribution. Try then with a source tarball distributed by the
-problematic upstream project or even directly from the source code
-repository.
-
-Troubleshooting
---------------
-
-If you need to install Meson "manually":
-```bash
 virtualenv -p python3 ./ # Create virtualenv
 source bin/activate      # Activate the virtualenv
-pip3 install meson       # Install Meson
+pip install meson        # Install Meson
 hash -r                  # Refresh bash paths
 ```

-If you need to install Ninja "manually":
-```bash
+Finally download and build Ninja locally:
+```
 git clone git://github.com/ninja-build/ninja.git
 cd ninja
 git checkout release
 ./configure.py --bootstrap
-mkdir ../bin
+mkdir ../bin                      
 cp ninja ../bin
 cd ..
 ```

+Compilation
+-----------
+
+Once all dependencies are installed, you can compile kiwix-lib with:
+```
+mkdir build
+meson . build
+cd build
+ninja
+```
+
+By default, it will compile dynamic linked libraries. If you want
+statically linked libraries, you can add `--default-library=static`
+option to the Meson command.
+
+Depending of you system, `ninja` may be called `ninja-build`.
+
+Installation
+------------
+
+If you want to install the libraries you just have compiled on your
+system, here we go:
+
+```
+ninja install
+cd ..
+```
+
+You might need to run the command as root, depending where you want to
+install the libraries.

-====================

-Introduction
------------
-
-libkiwix is written in C++. To use the library, you need the include files of libkiwix have
-to link against libzim.
-
-Errors are handled with exceptions. When something goes wrong, libkiwix throws an error,
-which is always derived from std::exception.
-
-All classes are defined in the namespace kiwix.
-
-libkiwix is a set of tools to manage zim files and provide some common functionnality.
