-### Database Initialization
+Database Initialization
+-----------------------
 
 The InfluxDB image contains some extra functionality for initializing a database. These options are not suggested for production, but are quite useful when running standalone instances for testing.
 
 The database initialization script will only be called when running `influxd`. It will not be executed when running any other program.
 
-#### Environment Variables
+### Environment Variables
 
 The InfluxDB image uses several environment variables to automatically configure certain parts of the server. They may significantly aid you in using this image.
 
-##### INFLUXDB_DB
+#### INFLUXDB_DB
 
 Automatically initializes a database with the name of this environment variable.
 
-##### INFLUXDB_HTTP_AUTH_ENABLED
+#### INFLUXDB_HTTP_AUTH_ENABLED
 
 Enables authentication. Either this must be set or `auth-enabled = true` must be set within the configuration file for any authentication related options below to work.
 
-##### INFLUXDB_ADMIN_USER
+#### INFLUXDB_ADMIN_USER
 
 The name of the admin user to be created. If this is unset, no admin user is created.
 
-##### INFLUXDB_ADMIN_PASSWORD
+#### INFLUXDB_ADMIN_PASSWORD
 
 The password for the admin user configured with `INFLUXDB_ADMIN_USER`. If this is unset, a random password is generated and printed to standard out.
 
-##### INFLUXDB_USER
+#### INFLUXDB_USER
 
 The name of a user to be created with no privileges. If `INFLUXDB_DB` is set, this user will be granted read and write permissions for that database.
 
-##### INFLUXDB_USER_PASSWORD
+#### INFLUXDB_USER_PASSWORD
 
 The password for the user configured with `INFLUXDB_USER`. If this is unset, a random password is generated and printed to standard out.
 
-##### INFLUXDB_READ_USER
+#### INFLUXDB_READ_USER
 
 The name of a user to be created with read privileges on `INFLUXDB_DB`. If `INFLUXDB_DB` is not set, this user will have no granted permissions.
 
-##### INFLUXDB_READ_USER_PASSWORD
+#### INFLUXDB_READ_USER_PASSWORD
 
 The password for the user configured with `INFLUXDB_READ_USER`. If this is unset, a random password is generated and printed to standard out.
 
-##### INFLUXDB_WRITE_USER
+#### INFLUXDB_WRITE_USER
 
 The name of a user to be created with write privileges on `INFLUXDB_DB`. If `INFLUXDB_DB` is not set, this user will have no granted permissions.
 
-##### INFLUXDB_WRITE_USER_PASSWORD
+#### INFLUXDB_WRITE_USER_PASSWORD
 
 The password for the user configured with `INFLUXDB_WRITE_USER`. If this is unset, a random password is generated and printed to standard out.
 
-#### Initialization Files
+### Initialization Files
 
 If the Docker image finds any files with the extensions `.sh` or `.iql` inside of the `/docker-entrypoint-initdb.d` folder, it will execute them. The order they are executed in is determined by the shell. This is usually alphabetical order.

 To manually initialize the database and exit, the `/init-influxdb.sh` script can be used directly. It takes the same parameters as the `influxd run` command. As an example:
