+### Link your PHP application to your MySQL database
 
 It is actually quite simple. In your Apache container, the hostname of the MySQL database is equal to the variable's value `MYSQL_SERVICE_NAME` defined in the `.env` file. Also, just use the port `3306` and the credentials defined in the `.env` file. 
 
-## Manage your database
+### Manage your database
 
 The simplest way is to access directly to the MySQL cli using `make mysql-cli`.
 
 If you want to manage your database with a more powerful tool (like MySQL Workbench), open your `.env` file in your favorite editor, set the variable `MYSQL_ENABLE_PORTS_MAPPING=1`, update if needed the variable `MYSQL_HOST_PORT_TO_MAP` and finally run `make kickoff`.
 
 You are now able to access on your host to your MySQL database using `127.0.0.1` and the port defined in the variable `MYSQL_HOST_PORT_TO_MAP`. See also: [Use MySQL Workbench to manage your database](docs/mysql_workbench.md)
