| MODS | ` ` | FALSE | This is an array of mods separated by comma and a new line. [Click Here for Examples](./docs/getting_started_with_mods.md) Supported files are `zip`, `dll`, and `cfg`. |
| AUTO_UPDATE | `0` | FALSE | Set to `1` if you want your container to auto update! This means at the times indicated by `AUTO_UPDATE_SCHEDULE` it will check for server updates. If there is an update then the server will be shut down, updated, and brought back online if the server was running before. |
| AUTO_UPDATE_SCHEDULE | `0 1 * * *` | FALSE | This works in conjunction with `AUTO_UPDATE` and sets the schedule to which it will run an auto update. [If you need help figuring out a cron schedule click here]
| AUTO_UPDATE_PAUSE_WITH_PLAYERS | `0` | FALSE | Does not process an update for the server if there are players online. |
| AUTO_BACKUP | `0` | FALSE | Set to `1` to enable auto backups. Backups are stored under `/home/steam/backups` which means you will have to add a volume mount for this directory. |
| AUTO_BACKUP_SCHEDULE | `*/15 * * * *` | FALSE | Change to set how frequently you would like the server to backup. [If you need help figuring out a cron schedule click here].
| AUTO_BACKUP_REMOVE_OLD | `1` | FALSE | Set to `0` to keep all backups or manually manage them. |
