+Documentation
+=============
+
+This section explains how to use and develop the LTP documentation. The current
+documentation format is written using
+`reStructedText <https://www.sphinx-doc.org/en/master/usage/restructuredtext/index.html>`_
+and it's built on top of `Sphinx <https://www.sphinx-doc.org/en/master/>`_.
+
+Building documentation
+~~~~~~~~~~~~~~~~~~~~~~
+
+First of all, to build the documentation we must be sure that all dependences
+have been installed (please check ``doc/requirements.txt`` file). Sometimes the
+Linux distros are providing them, but the best way is to use ``virtualenv``
+command as following:
+
+.. code-block:: bash
+
+    cd doc
+
+    # prepare virtual enviroment
+    python -m virtualenv .venv
+    source .venv/bin/activate
+
+    pip install sphinx
+    pip install -r requirements.txt
+
+    # build documentation
+    make
+
+Once the procedure has been completed, documentation will be visible at
+``doc/html/index.html``.
+
+.. warning::
+
+    The current ``.readthedocs.yml`` workflow is using ``Python 3.6`` because
+    other Python versions were causing issues. No other version has been tested,
+    but it should work anyway.
+
+Validating spelling
+~~~~~~~~~~~~~~~~~~~
+
+To check documentation words spelling, we provide support for
+`aspell <http://aspell.net/>`_, so make sure that it's installed. The
+documentation can be tested via ``make spelling`` command. Output will be
+visible in the ``doc/build`` folder and, if any error will be found, a warning
+message will be shown.
