Getting Started
****************
Get your API Keys
==================
1. Register to get an API Key at the `Random Stuff API resgistration page <https://api-docs.pgamerx.com/Getting%20Started/register/>`_. This is used for authentication.
2. Register at `RapidAPI <https://rapidapi.com/pgamerxdev/api/random-stuff-api>`_ for a RapidAPI Key and Account, and subscribe to the Random Stuff API. This is used to make requests to the Random Stuff API and keep track of them. You can go to `The RapidAPI Developer Dashboard <https://rapidapi.com/developer/apps>`_ after logging in, select an application, head over to security, and copy its key. This is your RapidAPI Key.
Examples
========
.. code-block:: python
import yarsaw
import asyncio # builtin, used for asynchronous calls
client = yarsaw.Client("your_api_key", "your_rapidapi_key")
async def joke():
joke = await client.get_joke() # get the joke in form of a dict
formatted_joke = yarsaw.Utils().format_joke(joke) # format the joke (optional)
print(formatted_joke) # print the joke
asyncio.get_event_loop().run_until_complete(joke()) # run the joke() function
Now just start reading the documentation!

The :doc:`client` page contains all of the methods you can use to interact with the Random Stuff API, so we recommend reading that first.

I want Welcome to YARSAW to be the first chapter, the next file to be the next. Instead, the subtitles become the chapters, and all the other content becomes subtitle.
I followed convention syntax from https://readthedocs.org/projects/documentation-style-guide-sphinx/downloads/pdf/latest/.
It works fine on the docs page itself (https://yarsaw.namantech.me).
Changing heading signs does not work.

[SOLVED]
The problem was that the toctree was below headers, which caused issues. Moving to the top of the file solves it.
