The simple fact is this stuff isn't ready for anyone to be writing guides on how to use it.
Look, I don't want to fight anyone... I updated my gist two weeks ago to have a warning on the top echoing your sentiment. However, I just saw that you made this comment on it:
I tested these instructions on 3 different machines, in what way are they "wrong" and "filled with irrelevancies"? If there's a constructive comment to be made, wouldn't it be easier just to make it?
I'm excited about Switch homebrew and have been documenting some of the public stuff which has been dropping with little to no READMEs or instructions... Ironically, posting my link here has to be the most notoriety it's received (so not much!).
libtransistor provides light instructions on how to set it up, compile the examples, and run them in Mephisto.
libnx instructions just say
"Setup $DEVKITA64 in your environment."
If you google
"setup DEVKITA64", you get my instructions. I'm not going to take them down since they're useful to me, I put time and effort into them, and now it seems like a censorship issue. As far as I'm concerned, if you don't think DEVKITA64 is ready for prime time, you should take it up with the libnx readme.
I'm also not going to be linking my instructions anywhere else, so as long as official instructions come out, you shouldn't have to "worry" about them. I never saw any such instructions come out for the Wii U, however...
