Installation

Could someone please help me with getting my DNS setup. I'm not quite sure where to begin. I read the documentation and am still confused. Do I need to buy a mySQL license and cPanel license first? I'm wanting to try out Boonex so shouldn't it be free? I was given my domain and name servers but am now stuck.

Someone may give you a free phone, but you still have to pay to have it connected. 
You really sound like you need help, so I suggest you forget doing it alone and sign up for a server such as Zarconia. I use them, they are excellent and they will install Dolphin for you. I'm not sure of the rates, but you can find out here:

If you insist on doing it alone, here's basically what happens. The fact that you have name servers, means that you have dome part of this already:

1. Download Dolphin - Free
2. Download and install an FTP client - considered essential. I use WINSCP
3. Choose a hosting Service provider. They need to supply the following in their hosting package:
   - MYSQL
   - PHP
   -Apache
   - A Control Panel (Can be CPanel)
   -Service (Dolphin is quirky and needs certain PHP functions to be activated.)
4. Obtain a Domain name (Sounds Like You've Done This)
   - Go to your control Panel and enter your Name Server details and Domain details.
   - Wait 48 hours for the Domain to appear on the Internet.
   - While on the Control Panel, select PHPMyAdmin and create a database. Remember the name,      username and password..
   - Check regularly by typing http://mydomainname.com or whatever.
   - When you see a page saying the domain exists, you are ready to boogy/
5. Open WINSCP and FTP (copy) Dolphin to the Home Directory of your server.
6. Enter Http://mydomainname.com again and a Dolphin splash page should appear. It will ask you to install Dolphin.
   - Do the install using the database name, user and password you created above.
   - Set up a Cron Job
   - Dolphin should now run.
   
   

Or for a few dollars someone at Zarconia will do all this for you and more!
