How should I document my Codeigniter web app?

Using PEAR phpDoc is always useful since you can create a function overview easily with e.g. doxygen so you know exactly what every function does.

Furthermore I love using http://revaxarts-themes.com/documenter to write beautiful "human readable" documentations like the CI user's guide.

At the moment I am also developing some "IgnitedDocs"-App that will allow developers to easily create CI docs with an interface similiar to theDocumenter but using the CI layout and supporting many docs with print and zip export as well. Hopefully I'll get it finished soon since I need it, too
