+Generation of SECRET_KEY
+------------------------
+
+Sometimes you need to generate a new ``SECRET_KEY`` so now you can generate it using this command:
+
+    $ python manage.py generate_secret_key
+
+
+1. ``--length`` – is the length of the key ``default=50``
+2. ``--alphabet`` – is the alphabet to use to generate the key ``default=ascii letters + punctuation symbols``
