# Auto-download from Modrinth

[Modrinth](https://modrinth.com/) is an open source modding platform with a clean, easy to use website for finding [Fabric, Forge, etc mods](https://modrinth.com/mods) and [Paper, etc plugins](https://modrinth.com/plugins), and [datapacks](https://modrinth.com/datapacks). 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.

- **MODRINTH_PROJECTS** : comma or newline separated list of project slugs (short name) or IDs. The project ID is located in the "Technical information" section. The project slug is the part of the URL that follows `/mod/`, `/plugin/`, or `/datapack/`. For example:
  ```
    https://modrinth.com/mod/fabric-api
                             ----------
                              |
                              +-- project slug
  ```
  Also, a specific version (or release type) can be declared adding a colon and then the version id, version number/name, or release type after the project slug. The version ID or number can be found in the 'Metadata' section. Valid release types are `release`, `beta`, `alpha`.
  
  To select a datapack from a Modrinth project, prefix the entry with "datapack:". When running a vanilla server, this is optional since only datapacks will be available for vanilla servers to select.
