+Authenticating with FunimationNow
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Like Crunchyroll, the FunimationNow plugin requires authenticating with a premium account to access some
+content: :option:`--funimation-email`, :option:`--funimation-password`. In addition, this plugin requires a ``incap_ses`` cookie to be
+sent with each HTTP request (see issue #2088); this unique session cookie can be found in your browser and sent via the :option:`--http-cookie` option.
+
+For example:
+
+.. sourcecode:: console
+
+    $ streamlink --funimation-email='xxx' --funimation-password='xxx' --http-cookie 'incap_ses_xxx=xxxx=' https://funimation.com/shows/show/an-episode-link
+
+.. note::
+
+    There are multiple ways to retrieve the required cookie.  For more
+    information on browser cookies, please consult the following:
