All we have about documentation is the wiki: http://zekr.org/wiki/.
There is a getting started document (written by Mohamed Fouad) for
checking out the sources from CVS and start development in Eclipse:

The best way to start is to checkout sources and launch the
application (net.sf.zekr.ZekrMain). You can then follow the classes
being used from the main method. Feel free to ask any questions
regarding source files.
By default there is a swt.jar in Zekr/lib on CVS, which is for win32
platform. If you have another platform, download the latest SWT here:
