+Settings
+========
+
+.. currentmodule:: django.conf.settings
+
+Django Discord Bind has a number of settings that control its behavior.
+
+
+Required Settings
+-----------------
+
+DISCORD_CLIENT_ID
+~~~~~~~~~~~~~~~~~
+
+The client identifier issued by the Discord authorization server.  This
+identifier is used in the authorization request of the OAuth 2.0
+Authorization Code Grant workflow.
+
+DISCORD_CLIENT_SECRET
+~~~~~~~~~~~~~~~~~~~~~
+
+A shared secret issued by the Discord authorization server.  This
+identifier is used in the access token request of the OAuth 2.0
+Authorization Code Grant workflow.
+
+Optional Settings
+-----------------
+
+DISCORD_AUTHZ_PATH
+~~~~~~~~~~~~~~~~~~
+
+    Default: ``/oauth2/authorize``
+
+The path of the authorization request service endpoint, which will be
+appended to the DISCORD_BASE_URI setting.
+
+DISCORD_BASE_URI
+~~~~~~~~~~~~~~~~
+
+    Default: ``https://discordapp.com/api``
+
+The base URI for the Discord API.

+
+The URI that the user will be redirected to after one or more successful
+auto-invites.
+
+DISCORD_REDIRECT_URI
+~~~~~~~~~~~~~~~~~~
+
+    Default: ``reverse('discord_bind_callback')``
+
+The URI that will be passed to the Discord authorization endpoint as the 
+URI for the callback route.  Normally this is determined by Django, but
+it can be set manually if the application is behind a proxy.
+
+DISCORD_RETURN_URI
+~~~~~~~~~~~~~~~~~~
+
+    Default: ``/``
+
+The URI that the user will be redirected to if no auto-invites are
+attempted or successful.
+
+DISCORD_TOKEN_PATH
