+\section intro_sec Introduction
+
+kvsdemo is a minimal, but well-documented reference implementation of
+a kviewshell plugin that can serve as a starting point for a
+real-world implementation.
+
+\section install_sec Usage
+
+When kvsdemo is installed, the kviewshell program can open C++ source
+files, i.e. files of mime type text/x-c++src. When such a file is
+loaded, kviewshell shows 10 blank pages of A4 size.
+ 
+\section content Content
+
+Only the two classes that are absolutely necessary for a working
+plugin are implemented. The only other file that is installed is a
+desktop file, which tells kviewhshell to use the plugin.
+
+- kvsdemo_multipage, an implementation of a kmultipage. In a real
+application, this class would create and manage the GUI elements that
+the plugin adds to the GUI of the kviewshell. This implementation adds
+nothing, and does only the minimal initialization required..
+
+- kvsdemo_renderer, an implementation of a documentRenderer. This
+class is responsible for document loading and rendering.
+
+- kvsdemo.desktop, the desktop entry file that tells KDE that kvsdemo
+is a plugin for kviewshell that handles files of type
+text/x-c++src. Without this file installed, the file dialog in
+kviewshell would not show C++ source files, and the command line
+"kvieshell test.cpp" would fail with an error dialog "No plugin for
+text/x-c++src files installed".
