QGIS Documentation will be built automatically on the server at 0, 8am, 4pm US/Pacific (Pacific Time). The current status is available at https://docs.qgis.org.
QGIS Documentation source files are available at https://github.com/qgis/QGIS-Documentation. They are mainly written using the reStructuredText (reST) format syntax, coupled with some scripts from the Sphinx toolset to post-process the HTML output. For general information on these tools, see http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html or https://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html.
The following chapters will guide you through learning:
how to modify the texts, provide screenshots... in a compliant way
how to share and ensure your modifications are pushed to the official docs.
If you are looking for general information about how to contribute to the QGIS project, you may find help at Get Involved in the QGIS Community.
