+Cogs
+======
+
+There comes a point in your bot's development when you want to organize a collection of commands, listeners, and some state into one class. Cogs allow you to do just that.
+
+The gist:
+
+- Each cog is a Python class that subclasses :class:`.Cog`.
+- Every command is marked with the :func:`.command` decorator or the corresponding shortcut command decorator.
+- Every listener is marked with the :meth:`.Cog.listener` decorator.
+- Cogs are then registered with the :meth:`.Bot.add_cog` call.
+- Cogs are subsequently removed with the :meth:`.Bot.remove_cog` call.
+
+Quick Example
+---------------
+
+This example cog defines a ``Greetings`` category for your commands, with a single slash command named ``hello`` as well as a listener to listen to an :ref:`Event <discord-api-events>`.
+
+.. code-block:: python3
+
+    class Greetings(discord.Cog):
+        def __init__(self, bot):
+            self.bot = bot
+            self._last_member = None
+
+        @discord.Cog.listener()
+        async def on_member_join(self, member):
+            channel = member.guild.system_channel
+            if channel is not None:
+                await channel.send(f'Welcome {member.mention}.')
+
+        @discord.slash_command()
+        async def hello(self, ctx, *, member: discord.Member = None):
+            """Says hello"""
+            member = member or ctx.author
+            if self._last_member is None or self._last_member.id != member.id:
+                await ctx.send(f'Hello {member.name}~')
+            else:
+                await ctx.send(f'Hello {member.name}... This feels familiar.')
+            self._last_member = member
+
+A couple of technical notes to take into consideration:
+
+- All listeners must be explicitly marked via decorator, :meth:`~.Cog.listener`.
+- The name of the cog is automatically derived from the class name but can be overridden.
+- All commands must now take a ``self`` parameter to allow usage of instance attributes that can be used to maintain state.
+
+Cog Registration
+-------------------
+
+Once you have defined your cogs, you need to tell the bot to register the cogs to be used. We do this via the :meth:`~.Bot.add_cog` method.
+
+.. code-block:: python3
+
+    bot.add_cog(Greetings(bot))
+
+This binds the cog to the bot, adding all commands and listeners to the bot automatically.
+
+Using Cogs
+-------------
+
+Just as we remove a cog by its name, we can also retrieve it by its name as well. This allows us to use a cog as an inter-command communication protocol to share data. For example:
+
+.. code-block:: python3
+    :emphasize-lines: 22,24
+
+    class Economy(discord.Cog):
+        ...
+
+        async def withdraw_money(self, member, money):
+            # implementation here
+            ...
+
+        async def deposit_money(self, member, money):
+            # implementation here
+            ...
+
+    class Gambling(discord.Cog):
+        def __init__(self, bot):
+            self.bot = bot
+
+        def coinflip(self):
+            return random.randint(0, 1)
+
+        @discord.slash_command()
+        async def gamble(self, ctx, money: int):
+            """Gambles some money."""
+            economy = self.bot.get_cog('Economy')
+            if economy is not None:
+                await economy.withdraw_money(ctx.author, money)
+                if self.coinflip() == 1:
+                    await economy.deposit_money(ctx.author, money * 1.5)
