+DuckStation now supports using RAIntegration for cheevos instead of its own internal handler, which is useful for developing achievement sets.
+
+To use RAIntegration, you must be:
+ - Using the Qt frontend.
+ - Using the x64 DuckStation build (there's no RAIntegration binaries for ARM64).
+ - Using the Windows build (there's no RAIntegration for other platforms).
+
+To enable:
+
+1. Download `RA_Integration-x64.dll` from retroachievements.org. We have specifically disabled the auto-downloading in RAInterface, because it doesn't use TLS, and is therefore not safe to download and execute code since it's vulnerable to MITM attacks. Link: https://retroachievements.org/bin/RA_Integration-x64.dll
+2. Rename `RA_Integration-x64.dll` to `RA_Integration.dll`, and move it into the DuckStation binary directory (same place with the other exes).
+3. Open `settings.ini` in the [User Directory](https://github.com/stenzek/duckstation#user-directories).
+4. Find the `[Cheevos]` section, and change `UseRAIntegration` to `true` (`UseRAIntegration = true`). If you're not using a new install, this line won't exist, and you'll have to add it.
+5. Start DuckStation as normal. You will be prompted to log in to RetroAchivements the first time you start.
+6. Enable the debug menu (`Advanced Settings -> Show Debug Menu`), and there will be a `RAIntegration` submenu at the top which you can use to interact with RAIntegration.
