How do I install HomeBrew for Wii and Clean Rip?

[StrikeHedgehog]

So I decided I'm gonna attempt to rip some models off some of my games.And what I want to do is Rip the ISO off the game disk so I'm not doing anything that breaks the ROM laws.But I want to make sure I don't brick my wii in the process.Im gonna then use the Dolphin emulator to extract the models on my Mac.Whats the safest way to install the neccasary software and can I get a step by step instructions?

Main Questions:

1. What is the safest way to install the HomeBrew Channel without destroying my Wii?

2. What are the step-by-step instructions for that process?

3.How do I extract the Files?

4. Can I extract the models via the Dolphin Emulator?
