Hi

Yes, the developer and user guides live a somewhat trist live beside the
main source code repository. But you can easily change the content, by
submitting a merge request. Both are generated by the sources underneath
/docbook inside the repository. wsug is the directory for the user guide
and wsdg the one for the development guide.

kind regards
Roland
