-## Run a functional test of MySQL on Azure Cobalt 100

-After installing MySQL on your Arm64 virtual machine, you can perform simple baseline testing to validate that MySQL runs correctly and produces the expected output.
+After installing MySQL on your Azure Cobalt 100 Arm64 virtual machine, you should run a functional test to confirm that the database is operational and ready for use. Beyond just checking service status, validation ensures MySQL is processing queries correctly, users can authenticate, and the environment is correctly configured for cloud workloads.
 
 ### Start MySQL 
 
-Make sure MySQL is running: 
+Ensure MySQL is running and configured to start on boot:
 
 ```console
 sudo systemctl start mysql
 sudo systemctl enable mysql

 ### Connect to MySQL 
 
+Connect using the MySQL client:

 ```console
 mysql -u admin -p
 ```
-Opens the MySQL client and connects as the new user(admin), prompting you to enter the admin password.

+After creating and selecting a database, the next step is to define a table, which represents how your data will be structured. In MySQL, tables are the core storage objects where data is inserted, queried, and updated.
