Need help installing kodi on smart tv

I apologize in advance as this is probably not the right place to start this thread (If someone can tell me where to post this question I will gladly move it)

I am wanting to install Kodi on my Vizio smart tv Via USB flash drive. I am unsure as how to do this, as what videos I have found so far are not very helpful at all. I would love for someone to be able to help me out step by step or even send me in the right direction of a video tutorial that is correct.
