# AutoTune Core
AutoTune Core is the shared library and compatibility layer used by AutoTune mods.
It does not try to replace performance mods by itself. Instead, it provides common code, loader support, configuration helpers, and shared systems used by mods such as AutoTune FPS.
## What it does
- Provides shared code for AutoTune mods
- Keeps Fabric and NeoForge support consistent
- Helps AutoTune FPS and future AutoTune mods use the same core systems
- Reduces duplicated code between loaders and Minecraft versions
## Do I need this?
You only need AutoTune Core if another AutoTune mod requires it.
For example, AutoTune FPS uses AutoTune Core as a required dependency. Install AutoTune Core together with AutoTune FPS when the version page says it is required.
## Supported loaders
- Fabric
- NeoForge

- 1.21

## Important
AutoTune Core is mainly a dependency mod. Installing it alone usually will not add visible gameplay features.
For performance features, install AutoTune FPS together with the required matching AutoTune Core version.
