+
+A Primer to Gateway Intents
+=============================
+
+In version 1.5 comes with the introduction of :class:`Intents`. This is a radical change in how bots are written. An intent basically allows a bot to subscribe into specific buckets of events. The events that correspond to each intent is documented in the individual attribute of the :class:`Intents` documentation.
+
+These intents are passed to the constructor of :class:`Client` or its subclasses (:class:`AutoShardedClient`, :class:`~.AutoShardedBot`, :class:`~.Bot`) with the ``intents`` argument.
+
+If intents are not passed, then the library defaults to every intent being enabled except the privileged intents, currently :attr:`Intents.members` and :attr:`Intents.presences`.
+
+What intents are needed?
+--------------------------
+
+The intents that are necessary for your bot can only be dictated by yourself. Each attribute in the :class:`Intents` class documents what :ref:`events <discord-api-events>` it corresponds to and what kind of cache it enables.
+
+For example, if you want a bot that functions without spammy events like presences or typing then we could do the following:
+
+.. code-block:: python3
+
+ import discord
+ intents = Intents(typing=False, presences=False)
+
+Note that this doesn't enable :attr:`Intents.members` since it's a privileged intent.
+
+Another example showing a bot that only deals with messages and guild information:
+
+.. code-block:: python3
+
+ import discord
+ intents = discord.Intents(messages=True, guilds=True)
+ # If you also want reaction events enable the following:
+ # intents.reactions = True
+
+.. _privileged_intents:
+
+Privileged Intents
+---------------------
+
+With the API change requiring bot authors to specify intents, some intents were restricted further and require more manual steps. These intents are called **privileged intents**.
+
+A privileged intent is one that requires you to go to the developer portal and manually enable it. To enable privileged intents do the following:
+
+1. Make sure you're logged on to the `Discord website <https://discord.com>`_.
+2. Navigate to the `application page <https://discord.com/developers/applications>`_
+3. Click on the bot you want to enable privileged intents for.
+4. Navigate to the bot tab on the left side of the screen.

+
+5. Scroll down to the "Privileged Gateway Intents" section and enable the ones you want.

+
+.. warning::
+
+ Enabling privileged intents when your bot is in over 100 guilds requires going through `bot verification <https://support.discord.com/hc/en-us/articles/360040720412>`_. If your bot is already verified and you would like to enable a privileged intent you must go through `discord support <https://dis.gd/contact>`_ and talk to them about it.
+
+Do I need privileged intents?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is a quick checklist to see if you need specific privileged intents.
+
+Presence Intent
++++++++++++++++++
+
+- Whether you use :attr:`Member.status` at all to track member statuses.
+- Whether you use :attr:`Member.activity` or :attr:`Member.activities` to check member's activities.
+
+Member Intent
++++++++++++++++
+
+- Whether you track member joins or member leaves, corresponds to :func:`on_member_join` and :func:`on_member_remove` events.
+- Whether you want to track member updates such as nickname or role changes.
+- Whether you want to track user updates such as usernames, avatars, discriminators, etc.
+- Whether you want to request the guild member list through :meth:`Guild.chunk` or :meth:`Guild.fetch_members`.
+- Whether you want high accuracy member cache under :attr:`Guild.members`.
+
+Member Cache
+-------------
+
+Along with intents, Discord now further restricts the ability to cache members and expects bot authors to cache as little as is necessary. However, to properly maintain a cache the :attr:`Intents.members` intent is required in order to track the members who left and properly evict them.
+
+To aid with member cache where we don't need members to be cached, the library now has a :class:`MemberCacheFlags` flag to control the member cache. The documentation page for the class goes over the specific policies that are possible.
+
+It should be noted that certain things do not need a member cache since Discord will provide full member information if possible. For example:
+
+- :func:`on_message` will have :attr:`Message.author` be a member even if cache is disabled.
+- :func:`on_voice_state_update` will have the ``member`` parameter be a member even if cache is disabled.
+- :func:`on_reaction_add` will have the ``user`` parameter be a member even if cache is disabled.
+- :func:`on_raw_reaction_add` will have :attr:`RawReactionActionEvent.member` be a member even if cache is disabled.
+- The reaction removal events do not have the member information. This is a Discord limitation.
+
+Other events that take a :class:`Member` will require the use of the member cache. If absolute accuracy over the member cache is desirable, then it is advisable to have the :attr:`Intents.members` intent enabled.
