The community is encouraged to update the QFS wiki as they wish. However, public
editing has been turned off on the github wiki itself. Instead, the wiki
documents are mirrored in the wiki directory of the QFS source code.
This allows for a few things:
- Wiki documentation is distributed along with the qfs source code
- The community can use pull requests to submit changes to the wiki
- The community can request updates to the wiki in the same pull request as code changes are made, keeping code and documentation in sync
If you would like to make a change to the wiki, please submit a pull request and we will be happy to accept it!
