The only requirements for contributing documentation updates to Fedora Docs are:
You can modify/edit documentation pages directly in your browser (without installing any new tools/software on your computer). For larger updates which may be easier to work on offline, you may also need the following:
A plaintext editor, preferably with AsciiDoc syntax highlighting to work on the documentation pages. e.g.,
git(see Git for docs writers).
Docker CEto test your changes offline.
