+Quickstart
+============
+
+This page gives a brief introduction to the library. It assumes you have the library installed,
+if you don't check the :ref:`installing` portion.
+
+A Minimal Bot
+---------------
+
+Let's make a bot that replies to a specific message and walk you through it.
+
+It looks something like this:
+
+.. code-block:: python
+
+    import discord
+
+    client = discord.Client()
+
+    @client.event
+    async def on_ready():
+        print('We have logged in as {0.user}'.format(self))
+
+    @client.event
+    async def on_message(message):
+        if message.author == client.user:
+            return
+
+        if message.content.startswith('$hello'):
+            await message.channel.send('Hello!')
+
+    client.run('your token here')
+
+Let's name this file ``example_bot.py``. Make sure not to name it ``discord.py`` as that'll conflict
+with the library.
+
+There's a lot going on here, so let's walk you through it step by step.
+
+1. The first line just imports the library, if this raises a `ModuleNotFoundError` or `ImportError`
+   then head on over to :ref:`installing` section to properly install.
+2. Next, we create an instance of a :class:`Client`. This client is our connection to Discord.
+3. We then use the :meth:`Client.event` decorator to register an event. This library has many events.
+   Since this library is asynchronous, we do things in a "callback" style manner.
+
+   A callback is essentially a function that is called when something happens. In our case,
+   the :func:`on_ready` event is called when the bot has finished logging in and setting things
+   up and the :func:`on_message` event is called when the bot has received a message.
+4. Since the :func:`on_message` event triggers for *every* message received, we have to make
+   sure that we ignore messages from ourselves. We do this by checking if the :attr:`Message.author`
+   is the same as the :attr:`Client.user`.
+5. Afterwards, we check if the :class:`Message.content` starts with ``'$hello'``. If it is,
+   then we reply in the channel it was used in with ``'Hello!'``.
+6. Finally, we run the bot with our login token. If you need help getting your token or creating a bot,
+   look in the :ref:`discord-intro` section.
+
+
+Now that we've made a bot, we have to *run* the bot. Luckily, this is simple since this is just a
+Python script, we can run it directly.
+
+On Windows:
+
+.. code-block:: shell
+
+    $ py -3 example_bot.py
+
+On other systems:
+
+.. code-block:: shell
+
+    $ python3 example_bot.py
+
+Now you can try playing around with your basic bot.
