You need to extract the files and put them all (including dbc.php) in the same place. Then create a database in your cpanel with any name and assign it a user, and run the sql queries posted on that page. After that open dbc.php and edit in the database value Then point your browser to register.php and register a user. I think after that you will get an email on the address you used to register to activate your account and login.
Let me know if there are any problems and I will be happy to explain more.
i have already extracted the files and created the database with the queries given, but i dont understand how i get it onto the website. what and where should i put it in the html?
Do you mean you already got a website and you want to integrate the login/registration pages into your website?
