MySql with ERPNext

Hi All,
Happy new year,
I was using and learning this ERPnext from last 10-15 days.
This is a really great framework.
My Problem is that can i create site and app using MySql latest version as i have searched and find it only supports mariaDB and postgres as beta.

Only MariaDB is supported for now. Postgre is still in beta as you said…

MariaDB is also MYSql. You can use all the same commands in Mariadb. Then why do you need mysql?
