Hello,
the documentation has come a really long way. To make it complete we still need contributors, more specifically for the dataset, organisation unit, and user modules. Is there anyone in the HISP community who could make an effort with this?
The docs are now arranged based on system modules so the work would involve creating new chapters, eg dhis2_user_man_organisation_unit, and include it in dhis2_user_manual_en.xml
More instructions here: http://dhis2.org/sites/default/files/resources/dhis2_documentation_guide.pdf
