Echoing what Paul said in the other PR:

Hi! Let us know if you need any assistance in putting together a PR for this project.

As it looks like you are still working on this, you might want to covert it to a 'draft' PR. Then when you are ready for it to be reviewed, mark it as ready to review.

Again, feel free to ask questions. The Arcade discord is a good spot for getting quick info.

In general, I'd like to see the word joystick replaced with controller. Pyglet offers two controller APIs, one being controller and the other being joystick. This documentation is for the controller API, so it would be best if this document only referred to it as such to avoid confusion.

Just this one issue with the Sphinx build, other than that looks good, if you can update that I'd say this is good to merge.

There is a lingering issue with the sphinx build, but it's only slightly related to this PR, I will just go ahead and merge this and fix it.
