It's not very difficult.
1. Start by making your SQL database (write down the hostname (usually this is local host), database name, database user and password so that you don't forget them).
2.

3. Follow the steps
PM me cPanel login info and I'll install it for you if you want.
Step by step is already in the documentation that comes with MyBB, and on the Wiki.
