Need Help Installing Script On My Website

Hi everyone. My names Kevin. I’m installing LaraBux on my website and need help. I’m halfway through so far. I have very minimal coding knowledge so please bare with me. I’m on step 5 of the installation and am stuck. It says "Access the control panel of your server and configure your domain to point to the public folder of LaraBux by simply setting the Document Root property or Hosting Path .
/home/www/public/ " I don’t know how to set the Document Root property or Hosting Path. Any Help? Thanks in advance!
