How to play nkit iso games on HOMEBREW WII

Hi !
I am actually new to all these roms, homebrew,emulators etc. Earlier I simply used to play wii games using their original CD’s. But now my wii has stopped reading cds. Due to which I am unable to play games on wii.

Now as I want to play games in wii again, I heard of vimms lair and homebrew. But I have few questions, please answer:-

1. Can the nkit iso files of games installed from vimms lair run on wii homebrew? If yes then how?

2. Is home brew safe? If yes then how to homebrew my wii

If possible please take your time and post a complete guide/link/video regarding this. I have no experience dealing with such softwares.

Thanks and have a nice day !
