While it is unclear to me if it is a good idea to leave the Debian wiki when writing documentation, I leave that to others to figure out.
I just wanted to point out that when selecting source format for the documentation, I strongly recommend using a format that can be converted to docobok using pandoc, to be able to create good looking documentation in both HTML, PDF and ePub format. It is also a very good idea to ensure the format selected is well handled by po4a to allow the documents to be translated into non-English languages using the tools currently used by translators of both the Debian Edu documentation and free software, ref <URL: https://people.skolelinux.org/pere/blog/From_English_wiki_to_translated_PDF_and_epub_via_Docbook.html >. Note, since the blog post was written, we started using Hosted Weblate to handle most translations, see <URL: https://hosted.weblate.org/projects/debian-edu-documentation/ > for the current status. Personally I would recommend Restructured text (rst) over markdown, as it has a richer vocabulary than markdown. I recommend Restructured text over Asciidoc as the latter is less well supported by po4a. -- Happy hacking Petter Reinholdtsen
