This document was originally written by Martin Bless.

Special thanks to Xavier Perseguers, who wrote some of the original texts in the retired TYPO3 Wiki and elsewhere. Some of the texts have been incorporated into this document or at least served as a basis.

Further chapters like Common pitfalls, Cheat sheet: reST & Sphinx, Contribute to the TYPO3 documentation, Basic principles, How to document an extension and How You Can Help were added by Sybille Peters.

A number of other people have helped by reviewing and refining the text and pointing out missing information. For more contributors, see the list of contributors on GitHub for this manual.

We thank everyone for their help and hope that good documentation about writing documentation will make it easier for others to contribute.
