+Natural Language Tookkit module.
+
+To use this module, you will need to install nltk and spacy,
+Python modules and then install some data from English words:
+
+::
+
+   $ make develop
+
+If you would like to install works for another language set the
+variable ``LANG``. For example:
+
+::
+
+   $ make develop LANG=fr
+
+In order to use the Extended Open Multilingual Wordnet with NLTK and
+use even more languages, you need to install them manually. Go to
+`<http://compling.hss.ntu.edu.sg/omw/summx.html>`_, download the data,
+and then create a new folder under
+``$HOME/nltk_data/corpora/omw/your_language`` where you put the file
+from wiki/wn-wikt-your_language.tab, and rename it to
+wn-data-your_language.tab.
