Alright. Get a SD card and install the Bannerbomb installer on it.
http://bannerbomb.qoid.us/MAKE SURE YOUR SD CARD IS EMPTY.
Alright now download the Bootmii installer from:
http://www.bootmii.orgRename the dol file in there to boot.dol
Go to your Wii savedata
Go to SD Card
It will ask to load the boot.dol or not. Say yes.
Install Bootmii, Homebrew Channel, and DVDX
You need Bootmii to back up your NAND in case you get bricked for some reason, you need DVDX to read/play custom discs for DVDs or Homebrew in CD form, and you need Homebrew Channel to load everything else.
After you finish the installation for all of them, remove everything on your SD Card and make a apps folder. Download HomeBrew Browser there and now you can add Homebrew apps without leaving your wii! Just open Homebrew Browser from the Homebrew Channel.
I'm very thorough.
