XF 1.3 How do I build a Landing Page?

Hello, I am using the XendisConnect theme and are unsure of how to build a landing page for my forum. My forum is www.pafisherman.com

My question:
Do i create a new landin_template.php file or whats the process and how would i assign it as the 'home' page, I have to assume I could just copy the 'index.php' file's headers and footers to do the connections to the dbase for the user credentials etc and If this is the same for an 'self' created files.

Any help, advice, or links to tutorials would be greatly appreciated. Thank you in advance.
