+Building Documentation
+----------------------
+
+If you installed novelWriter from a package, the documentation should be included. If you're running
+novelWriter from the source code, a local copy of this documentation can be generated. It requires
+the following Python packages on Debian and Ubuntu.
+
+* ``python3-sphinx``
+* ``python3-sphinxcontrib.qthelp``
+
+Or from PyPi:
+
+.. code-block:: console
+
+   pip install sphinx sphinxcontrib-qthelp
+
+To build the help packages from the documentation source, run
+
+.. code-block:: console
+
+   ./setup.py qthelp
+
+from the root source folder.
