I assume you created an account (Free hosting)
-->Login to your cpanel
----->Online File Manager
------->Copy all your files into htdocs folder
You need to create a database
----->I belive it starts with your cpanel username
-------->In the Current Databases table you will see
MySQL DB Name ----MySQL User Name---MySQL Password(Your cPanel Password)---MySQL Host Name
Those data are required to install Q2A.
I think that's all you need.
