+Libkiwix programming
+====================
+
+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.

+Kiwix serve widget
+====================
+
+Introduction
+------------
+
+The kiwix-serve widget provides an easy to embed way to show the `kiwix-serve` homepage.
+
+Usage
+-----
+
+To use the widget, simply add an iframe with its `src` attribute set to the `widget` endpoint.
+Example HTML Page ::
+
+    <!DOCTYPE html>
+    <html lang="en">
+    <head>
+    <title>Widget Test</title>
+    </head>
+    <body>
+    <iframe src="http://192.168.18.8:8080/widget?disabledesc&disablefilter&disabledownload" width=1000 height=1000></iframe>
+    </body>
+    </html>
+
+This creates an iframe with the kiwix-serve homepage contents.
+
+Arguments are explained below.
+
+Possible Arguments
+-------------------
+
+Currently, the following arguments are supported.
+
+disabledesc (value = N/A)
+    Disables the description part of a tile.
+
+disablefilter (value = N/A)
+    Disables the search filters: language, category, tag and search function.
+
+disableclick (value = N/A)
+    Disables clicking the book to open it for reading.
+
+disabledownload (value = N/A)
+    Disables the download button (if avaialable at all) on the tile.
+
+
+Custom CSS and JS
+-----------------
+
+You can add your custom CSS rules and Javascript code to the widget.
+
+To do that, use the following code as template::
+
+    <iframe id="receiver" src="http://192.168.18.8:8080/widget?disabledesc=&disablefilter=&disabledownload=" width="1000" height="1000">
+    <p>Your browser does not support iframes.</p>
+    </iframe>
+
+    <script>
+    window.onload = function() {
+    var receiver = document.getElementById('receiver').contentWindow;
+    function sendMessage() {
+        let msg = {
+        css: `
+        .book__header {
+            color:red;
+        }`,
+        js: `
+        function widgetTest() {
+        console.log("Testing widget");
+        }
+        widgetTest();
+        `
+        }
+        receiver.postMessage(msg, 'http://192.168.18.8:8080/widget');
+    }
+    sendMessage();
+    }
+    </script>
+
+
+The CSS/JS fields are optional, you may send both or only one.

- *  - One for the embedded fulltext index, using a "empty" constructor and the
- *  `add_reader` method".
- *
- *  On top of that, the Searcher may (if compiled with ctpp2) be used to
- *  generate a html page for the search result. This use a template that need a
- *  humanReaderName. This feature is only used by kiwix-serve and this should be
