Kodi installation

Hai, I have frodo v12.2 .openlec 3.2.3.i and linux system. I do not know it, I used to buy a box and I bought xbmc. I wanted to install kodi, because from what I know what it has is already obsolete. How to install kodi, how do I enter the kodi website and choose a linux system because I think I have one, there is no download, and once I downloaded this system what I now have, installed on my finger and smig. I welcome.
