 ## Auto-download mods and plugins from Modrinth
 
 [Modrinth](https://modrinth.com/) is an open source modding platform with a clean, easy to use website for finding [Fabric and Forge mods](https://modrinth.com/mods). At startup, the container will automatically locate and download the newest versions of mod/plugin files that correspond to the `TYPE` and `VERSION` in use. Older file versions downloaded previously will automatically be cleaned up.
