+How do I make a web request?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To make a request, you should use a non-blocking library.
+This library already uses and requires a 3rd party library for making requests, ``aiohttp``.
+
+Quick example: ::
+
+    async with aiohttp.ClientSession() as session:
+        async with session.get('http://aws.random.cat/meow') as r:
+            if r.status == 200:

+See `aiohttp's full documentation <http://aiohttp.readthedocs.io/en/stable/>`_ for more information.
+
+How do I use a local image file for an embed image?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Discord special-cases uploading an image attachment and using it within an embed so that it will not
+display separately, but instead in the embed's thumbnail, image, footer or author icon.
+
+To do so, upload the image normally with :meth:`abc.Messageable.send`,
+and set the embed's image URL to ``attachment://image.png``,
+where ``image.png`` is the filename of the image you will send.
+
+
+Quick example: ::
+
+    file = discord.File("path/to/my/image.png", filename="image.png")
+    embed = discord.Embed()
+    embed.set_image(url="attachment://image.png")
+    await channel.send(file=file, embed=embed)
+
+.. note ::
+
+    Due to a Discord limitation, filenames may not include underscores.
+
+Is there an event for invites or audit log entries being created?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Since Discord does not dispatch this information in the gateway, the library cannot provide this information.
+This is currently a Discord limitation.
