ReinCore is the foundation of the Rein plugin ecosystem, providing the shared core functionality required by compatible Rein plugins. Designed to work behind the scenes, it allows supported plugins to rely on a common core instead of operating independently.
📦 **Requirements:** Java 21 and a compatible Paper server.
⚠️ **Important:** ReinCore is a dependency, not a standalone gameplay plugin. Install it in your server's `plugins/` directory alongside any Rein plugins that require it.
