 ### `MONGO_INITDB_ROOT_USERNAME`, `MONGO_INITDB_ROOT_PASSWORD`
 
-These variables are optional, used in conjunction to create a new user and to set that user's password. This user will be created in the `admin` authentication database and given the role of `root`. superuser permissions (see above) for the database specified by the `MYSQL_DATABASE` variable. Both variables are required for a user to be created. If both are present then Mongo will start with authentication enabled: `mongod --auth`. Authentication in MongoDB is fairly complex, so more complex user setup is explicitly left to the user via `/docker-entrypoint-initdb.d/` (see _Initializing a fresh instance_ below).

 Do note that MongoDB does not require authentication by default, but it can be configured to do so. For more details about the functionality described here, please see the sections in the official documentation which describe [authentication](https://docs.mongodb.com/manual/core/authentication/) and [authorization](https://docs.mongodb.com/manual/core/authorization/) in more detail.
 
 If you do create a root user, you will need to connect against the `admin` authentication database:

-This variable is optional and allows you to specify the name of a database to be used for creation scripts in `/docker-entrypoint-initdb.d/*.js` (see _Initializing a fresh instance_ below). MongoDB is fundamentally designed for "create on first use" so automating database creation does not make much sense.
