+`NaszaKlasa supports OAuth2`_ as their authentication mechanism. Follow these
+steps in order to use it:
+
+- Register a new application at your `NK Developers`_ (define the `Callback
+  URL` to ``http://example.com/complete/nk/`` where ``example.com``
+  is your domain).
+
+- Fill the ``Client ID`` and ``Client Secret`` values from the newly created
+  application::
+
+    SOCIAL_AUTH_NK_KEY = ''
+    SOCIAL_AUTH_NK_SECRET = ''
+
+- Enable the backend in ``AUTHENTICATION_BACKENDS`` setting::
+
+    AUTHENTICATION_BACKENDS = (
+        ...
+        'social.backends.nk.NKOAuth2',
+        ...
