RE: Kodi vs. Kodi Vanilla (help?)

Hi folks,

I joined here this week, posted a question, but it got removed due to it (inadvertently) violating forum rules. So I would like to re-post and re-phrase the question here please. I hope that I have posted this in the appropriate section!

I have a brand new Amazon Firestick. I would like to install Kodi on it but, from information I have gleaned on here, I think that Kodi is ILLEGAL and that you instead are to install Kodi VANILLA? The latter being the LEGITIMATE version?

Is this correct please?

Thanks,

Paul
