 `ADMINPASSWORD:` Sets or changes the admin password. Is mandatory at first startup or will fail. I recommend to remove it once the server is started because the server logs every argument in clear text (if doesn't cares, you can leave it).
 
+`PASSWORD:` Sets or changes server password. Is optional.

 `DEBUG:` Enable the debug mode in server
