Installation instructions on wiki
The installation instructions for the documentation ask to use "assistant -addContentFile ... ". However, Qt Assistant responds with an error message that this commandline option is not supported. Instead, I successfully installed the doc from within Qt Assistant by manually adding index.dcf (German version: Bearbeiten | Einstellungen -> Dokumentation -> Hinzufügen ...).
The path to index.dcf is also incorrect in the wiki (index.dcf is in subdirectory deploy/docs).
