For each statistic pane should described what the stat corresponds to and how values are computed.

For csv export, there should a summary of what each file corresponds to.

Quote from a site admin

For instance in https://tuleap.example.com/plugins/statistics/index.php I have no idea of what is a session ?
I don’t know as well how to see all user who have an access to Codex (whatever the access)
Git read acess are in a UI only, git push in a csv export only.

The plugins/statistics/data_export.php provide only a csv file which is impossible to import in excel because export of project description and several other field prevent import.
I think before we had the possibility to have a global view without csv. Now we have nothink.

A good documentation to me would give :

· service per service, what is possible to have in term of statistics.

· Globally (in a summarized way), what is possible to have at platform level.
