What's the best way to root my Fire? Can I put Cyanogenmod on it?

[JohnJSal]

Hi everyone. I just picked up an extra Kindle Fire 7 (2015) to mess around with rooting, but everything I'm finding online seems to be dated last year. Are there any up-to-date instructions for how to root the Fire, or do the old methods still work?

From my understanding, rooting doesn't actually change anything itself, such as the OS, but after rooting I can then change things like the launcher and OS? Is it possible to change the launcher without rooting?

Is Cyanogen or any other ROMs available for the Fire?

Thanks!
