Bootstrap won't help you.  If you're on a Linux server, you'll need knowledge in PHP and MySql databases. Also, it might be very helpful to set up a Local Testing server and PHP development environment.

Get one of the following servers for your OS and follow the installation instructions.

WAMP for Windows
