+Documentation
+-------------
+The documentation of the pEpPythonAdapter uses `Sphinx <https://www.sphinx-doc.org/>`_
+Refer to the `Sphinx installation instructions <https://www.sphinx-doc.org/en/master/usage/installation.html>`_ to install it.
+
+To generate the documentation in the HTML format, there is a make target "docs"
+But first, you need to create/activate the venv or set the LD_LIBRARY_PATH manually.
+
+``make venv``
+
+``make docs``
+
+You can see the generated HTML documentation in a browser opening the directory
+`docs/build/html`.
+
+Housekeeping
+------------
+There are the following "clean" targets.
+
+To delete all the generated documentation, run:
+
+``make docs-clean``
+
+To delete all the "derived" files including eggs, wheels, shared libs, build files and caches, run:
+
+``make clean``
+
+To delete all of make clean plus the venv (should equal a complete reset), run:
+``make clean-all``
