 # CREATE A MYSQL DATABASE
 #=================================================
-# If your app uses a MySQL database, you can use these lines to bootstrap
-# a database, an associated user and save the password in app settings
+ynh_print_info "Creating a MySQL database..."
+
+### Use these lines if you need a database for the application.
+### `ynh_mysql_setup_db` will create a database, an associated user and a ramdom password.
+### The password will be stored as 'mysqlpwd' into the app settings,
+### and will be available as $db_pwd
+### If you're not using these lines:
+###		- Remove the section "BACKUP THE MYSQL DATABASE" in the backup script
+###		- Remove also the section "REMOVE THE MYSQL DATABASE" in the remove script
+###		- As well as the section "RESTORE THE MYSQL DATABASE" in the restore script
