... I had to create new branches

darn it! I had a feeling that would be the case 😬

[quetzalliwrites]

of course you remembered to add the overview page! i LOVE YOU, you are sooo good at paying attention to the little details! ✨😄

[quetzalliwrites]

This guide is very well done and covers many important points for writing high-quality documentation! Your document is very comprehensive and well-structured, providing a great starting point for new contributors. ✨

IMHO, this is ready to merge @thulieblack.

However, please note that while I have approved this PR, I added a do not merge label because I think we need to create a feature branch for the Community Docs Style Guide work. Ideally, I think it makes more sense to have you and the other Style Guide contributors merge their work to a feature branch first, and then once all style guide content is done/ready in the feature branch and reviewed... we merge that feature branch to MAIN branch. (Let me know if that doesn't make sense.)

I just need to figure out how we do that first, so I will get back to you on this. I think we may need to just ask @AceTheCreator maybe? I think he already did this before see he can prob give instructions on how to proceed on creating a feature branch for us and how merging that works.
