+
+Creating a Bot Account
+========================
+
+In order to work with the library and the Discord API in general, we must first create a Discord Bot account.
+
+Creating a Bot account is a pretty straightforward process.
+
+1. Make sure you're logged on to the `Discord website <https://discordapp.com>`_.
+2. Navigate to the `application page <https://discordapp.com/developers/applications/me>`_
+3. Click on the "New App" button.
+
+    .. image:: /images/discord_new_app_button.png
+        :alt: The new app button.
+
+4. Give the application a name and a description if wanted and click "Create App".
+
+    - You can also put an avatar you want your bot to use, don't worry you can change this later.
+    - **Leave the Redirect URI(s) blank** unless are creating a service.
+
+    .. image:: /images/discord_new_app_form.png
+        :alt: The new application form filled in.
+5. Create a Bot User by clicking on the accompanying button and confirming it.
+
+    .. image:: /images/discord_create_bot_user_button.png
+        :alt: The Create a Bot User button.
+6. Make sure that **Public Bot** is ticked if you want others to invite your bot.
+
+    - You should also make sure that **Require OAuth2 Code Grant** is unchecked unless you
+      are developing a service that needs it. If you're unsure, then **leave it unchecked**.
+
+    .. figure:: /images/discord_finished_bot_user.png
+
+        How the Bot User options should look like for most people.
+
+7. Click to reveal the token.
+
+    - **This is not the Client Secret**
+
+    .. figure:: /images/discord_reveal_token.png
+
+        How the token reveal button looks like.
+
+And that's it. You now have a bot account and you can login with that token.
+
+.. _discord_invite_bot:
+
+Inviting Your Bot
+-------------------
+
+So you've made a Bot User but it's not actually in any server.
+
+If you want to invite your bot you must create an invite URL for your bot.
+
+First, you must fetch the Client ID of the Bot. You can find this in the Bot's application page.
+
+.. image:: /images/discord_client_id.png
+    :alt: The Bot's Client ID.
+
+Copy paste that into the pre-formatted URL:
+
+.. code-block:: none
+
+    https://discordapp.com/oauth2/authorize?client_id=YOUR_CLIENT_ID&scope=bot&permissions=0
+
+Replace ``YOUR_CLIENT_ID`` with the Client ID we got in the previous step. For example,
+in the image above our client ID is 312718641634213889 so the resulting URL would be
+https://discordapp.com/oauth2/authorize?client_id=312718641634213889&scope=bot&permissions=0
+(note that this bot has been deleted).
+
+Now you can click the link and invite your bot to any server you have "Manage Server" permissions on.
+
+Adding Permissions
+~~~~~~~~~~~~~~~~~~~~
+
+In the above URL, you might have noticed an interesting bit, the ``permissions=0`` fragment.
+
+Bot accounts can request specific permissions to be granted upon joining. When the bot joins
+the guild, they will be granted a managed role that contains the permissions you requested.
+If the permissions is 0, then no special role is created.
+
+This ``permissions`` value is calculated based on bit-wise arithmetic. Thankfully, people have
+created a calculate that makes it easy to calculate the permissions necessary visually.

+
+Feel free to use whichever is easier for you to grasp.
+
+If you want to generate this URL dynamically at run-time inside your bot and using the
+:class:`discord.Permissions` interface, you can use :func:`discord.utils.oauth_url`.
