The TYPO3 Maintenance Guide intends to support site owners (system administrators, integrators and also editors) in their daily work with TYPO3 websites.
We are still looking for motivated and talented TYPO3 enthusiasts, who want to be engaged with the creation of this essential TYPO3 documentation. This is YOUR chance to contribute to the TYPO3 project. Note that nobody expects that you write the whole document: TYPO3 inspires people to share and in this case it means we share the work load. There are several tasks involved in authoring an official documentation: planning, writing, creating screenshots, reviewing, proofreading, etc.
If you are interested, contact the project leaders Michael or Christopher or send an email to the TYPO3 Documentation mailing list
The TYPO3 Maintenance Guide was previously known as the Administrator's Guide and renamed in late September 2012 (see: discussion in the mailing list for further details).
