teamviewer on RevPI setup

Hi, 

I have a kunbus revpi device running raspbian jessie originally it came with Teamviewer on but I have since removed. please, can you help me with the reinstalling and setting up again? 

when it was working and your have login you could only see the Kunbus config web page I would like to change this to look at a node js web app I have running is this a case of just changing the port somewhere? 

cheers
