astrodocs, Announcing Astro Docs Docs (AD²) — all the documentation you need to contribute to Astro Docs!
https://contribute.docs.astro.build/
Whether it's your very first contribution to an open-source project, or you're translating our docs, or you're contributing a how-to recipe, or you're preparing the accompanying documentation for your new Astro feature... we have a guide for that!
Want to level up your open-source documentation skills? We even have guides for reviewing docs PRs: what we look for when we work with, and bring out the best in, your contributions to us.
If you want to contribute to @astro Docs, or you're looking for some guidance you can follow to create your own project's docs, we hope you'll find our resources helpful.
