How to get started with modding my Wii

Hi, I got a Wii from my local thrift store and was wondering what the process is to start modding it. I know it’s finicky and can be easily messed up. Can someone please point me into the right direction? I know that there’s lots of guides online but i just want to make sure I follow a trustworthy and updated one. Once it’s modded, how do you install games (I own physical copies of them dw)
