The Wiki section
Taiga provides its own, Markdown-enabled wiki. You can access it from the sidebar on the left unless an admin has disabled it in the Admin interface.
The Wiki on Taiga should only be used to document work that ordinarily has no other home. All user and contributor documentation should be published on the Fedora Docs site, and the Fedora Project Wiki is the correct choice if you need a wiki. Only use the Taiga Wiki for items that you feel need to be documented that would not fit in either of these places.
For full documentation of Taiga wiki capabilities and usage, see Taiga documentation.
