his videos are on youtube and videos are up to date and easy to follow.
he has a video on how to install homebrew via steelminer method.
also on a cfw install for 11.8, which is the same as 11.9.
thats how i got my homebrew launcher installed,
then i went to the jisagi.frogminer site for the rest.
and i know that im kind of stepping on cat's toes right now by mentioning those videos, but i just used the hombrew launcher video a week or so ago and they are accurate.
BUT
it is recomended to use one website only or, one guide and not use multiple guides for different steps.
