(closed/reopened to try to trigger cloudflare to deploy it as preview)

I've tried to go through the docs and add any missing pieces. I see you have plans for more advanced provider docs - which would be amazing!

I also think we need to improve the OG image previews, mostly by having a logo. @Atinux could you help with a logo, perhaps? 🙏

However, I think we probably could go ahead and merge as is so we can keep in sync with updates to the docs/features. What do you think @qwerzl?

@danielroe That would be great! I'm setting this PR to be ready for review.
