 Add new language
 ~~~~~~~~~~~~~~~~
 
-``pybabel init -i messages.pot -d searx/translations -l it``

 Update .po files
 ~~~~~~~~~~~~~~~~
 
-``./utils/update-translations.sh``
+.. code:: shell
+
+    ./utils/update-translations.sh
 
 You may have errors here. In that case, edit the
 ``update-translations.sh`` script to change ``pybabel`` to
-``pybabel-python2``
+``pybabel-python2`` or ``pybabel2``
 
 After this step, you can modify the .po files.
