Welcome to the RetroAchievements documentation project!
First of all, you must know and adhere the User's Code of Conduct.
If you're looking for docs about creating achievements, check our Developer docs section.
We encourage all community members to join our Discord Server, we use this for most communication.
The complete list of pages is on the sidebar, but here's a brief description of some of them:
Downloads: our alternative downloads page.
Free Games: games that are completely and legally free download and play on your emulators.
My game is not loading achievements: what you have to do when your game isn't loading achievements.
Why you shouldn't use the load state feature: why you should expect to have issues if you use save/load state while playing.
A message for Achievement Hunters and Completionists about revisions: why you shouldn't be frustrated when a revision on an achievement set is made.
How to contribute if you are not a developer: if you don't know how to develop achievements, there are many other ways to contribute with the community.
You can help to improve these docs editing/creating the pages at RetroAchievements wiki.
