I'm a newbie and i have a project on creating a website with a rating systemI have downloaded the free version of the Star Rating System and i am lost on what to do after that. May i know where should i place the files and how do i able to connect to my database? I am using the Apache server and also MySql Database. Thank You.

You should read the index.html file inside for a step by step instruction.

How to install:
Unzip this file into your directory. Edit config.inc.php and setup database URL, and path informations.
Create/Setup database using database.sql file. You need to use phpMyAdmin for dumping SQL file in database, most of control panels have this.

I couldn't find what and where is phpMyAdmin. =(

In your hosting control panel?
If you cannot install, we can help you on free version install, but there is a small 15USD fee.
