How to contribute to the documentation?
We're in a bit of a transition phase at the moment with the tools we use for writing documentation.

The authoritative user and admin guide is here: https://github.com/civicrm/civicrm-user-guide.


fork the repository (you'll need a github account to do that)
make the edit directly on your fork of the repository
submit a pull request back to the original repository with a summary of your edit, why you made it, etc.


If it is a small edit, then the above is all you need to do. If it is a larger edit (or if you just feel like it) then you probably want to submit a documentation ticket on jira to discuss what you are planning on doing https://issues.civicrm.org/jira/secure/CreateIssue!default.jspa

If you think that you'll be making a few edits, then here's a bit more reading that you might find useful.
