 ## Environment Variables
 
+*If you are trying to backup a database that doesn't have a user or a password (you should!) make sure you set `CONTAINER_ENABLE_DOCKER_SECRETS=FALSE`*

 Along with the Environment Variables from the [Base image](https://hub.docker.com/r/tiredofit/alpine), below is the complete list of available options that can be used to customize your installation.
 
 
 | Parameter | Description |
 |-----------|-------------|
 | `BACKUP_LOCATION` | Backup to `FILESYSTEM` or `S3` compatible services like S3, Minio, Wasabi - Default `FILESYSTEM`
-| `COMPRESSION` | Use either Gzip `GZ`, Bzip2 `BZ`, XZip `XZ`, or none `NONE` - Default `GZ`
+| `COMPRESSION` | Use either Gzip `GZ`, Bzip2 `BZ`, XZip `XZ`, ZSTD `ZSTD` or none `NONE` - Default `GZ`
+| `COMPRESSION_LEVEL` | Numberical value of what level of compression to use, most allow `1` to `9` except for `ZSTD` which allows for `1` to `19` - Default `3` |
 | `DB_TYPE` | Type of DB Server to backup `couch` `influx` `mysql` `pgsql` `mongo` `redis` `rethink`
 | `DB_HOST` | Server Hostname e.g. `mariadb`
 | `DB_NAME` | Schema Name e.g. `database`

 | | Relative +MM, i.e. how many minutes after starting the container, e.g. `+0` (immediate), `+10` (in 10 minutes), or `+90` in an hour and a half
 | `DB_CLEANUP_TIME` | Value in minutes to delete old backups (only fired when dump freqency fires). 1440 would delete anything above 1 day old. You don't need to set this variable if you want to hold onto everything.
 | `DEBUG_MODE` | If set to `true`, print copious shell script messages to the container log. Otherwise only basic messages are printed.
+| `EXTRA_OPTS` | If you need to pass extra arguments to the backup command, add them here e.g. "--extra-command"
 | `MD5` | Generate MD5 Sum in Directory, `TRUE` or `FALSE` - Default `TRUE`
 | `PARALLEL_COMPRESSION` | Use multiple cores when compressing backups `TRUE` or `FALSE` - Default `TRUE` |
 | `SPLIT_DB` | If using root as username and multiple DBs on system, set to TRUE to create Seperate DB Backups instead of all in one. - Default `FALSE` |
