+### Setup
 
 * Download the latest version of the **Java Development Kit** from the website according to your OS. You can refer to [this website](http://www.oracle.com/technetwork/java/javase/downloads/jdk9-downloads-3848520.html) for JDK 9. 
 * Download the latest version of **MySQL** from [this website](https://dev.mysql.com/downloads/mysql/) according to your OS. You can refer to the installation steps accordingly. 
 	* Do not forget to change the default password of MySQL. 
 	* Check if you have installed MySQL successfully by running the following command on your terminal : 
-		```mysql
+		```
 			usr/local/mysql/bin/mysql -uroot -p
 		```
 	  After this, enter the new password you have created. This also verifies whether your new password has been successfully created or not. 
 * Once you are done setting up Java and MySQL on your machine, download any of the MySQL connectors compatible with Java. You can either download the ODBC or the JDBC connector. I have downloaded JDBC from [this website](https://dev.mysql.com/downloads/connector/).
