 ## Initial database setup
 
-    # Install the database packages
-    sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev
-
-    # Ensure you have MySQL version 5.5.14 or later
-    mysql --version
+```
+# Install the database packages
+sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev
 
-    # Pick a MySQL root password (can be anything), type it and press enter
-    # Retype the MySQL root password and press enter
+# Ensure you have MySQL version 5.5.14 or later
+mysql --version
 
-    # Secure your installation
-    sudo mysql_secure_installation
+# Pick a MySQL root password (can be anything), type it and press enter
+# Retype the MySQL root password and press enter
 
-    # Login to MySQL
-    mysql -u root -p
+# Secure your installation
+sudo mysql_secure_installation
 
-    # Type the MySQL root password
+# Login to MySQL
+mysql -u root -p
 
-    # Create a user for GitLab
-    # do not type the 'mysql>', this is part of the prompt
-    # change $password in the command below to a real password you pick
-    mysql> CREATE USER 'git'@'localhost' IDENTIFIED BY '$password';
+# Type the MySQL root password
 
-    # Ensure you can use the InnoDB engine which is necessary to support long indexes
-    # If this fails, check your MySQL config files (e.g. `/etc/mysql/*.cnf`, `/etc/mysql/conf.d/*`) for the setting "innodb = off"
-    mysql> SET storage_engine=INNODB;

+# Ensure you can use the InnoDB engine which is necessary to support long indexes
+# If this fails, check your MySQL config files (e.g. `/etc/mysql/*.cnf`, `/etc/mysql/conf.d/*`) for the setting "innodb = off"

-    # Grant the GitLab user necessary permissions on the database
-    mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, CREATE TEMPORARY TABLES, DROP, INDEX, ALTER, LOCK TABLES, REFERENCES ON `gitlabhq_production`.* TO 'git'@'localhost';

-    # You should now see a 'mysql>' prompt
+# Type the password you replaced $password with earlier
 
-    # Quit the database session

 ### MySQL utf8mb4 support
 
 After installation or upgrade, remember to [convert any new tables](#convert) to `utf8mb4`/`utf8mb4_general_ci`.
