Installation on a Chromebook?

Greetings!
I have recently bought myself a Lenovo N23 Yoga Chromebook.
The website “guides” me to download the linux version of popcorn which I did BUT I have no idea what to do with it.
Can anyone please help me?

As far as the android versions from what I read it is necessary to turn on the developer mode which wipes out everything and leaves the chromebook exposed to threats.

I would really appreciate it if anyone could guide me on what to do - how to install popcorn with using the linux files please.

Thank you in advance
