I have not worked it out, too many times a search ended at GitHub; it’s like the great filter for me, I cannot for the life of me get past it.
Similar/ related Linux instructions are often the same. Just do the gobbiligoo and write magicmumbojumbo in the wolooolooo. It is often just presumed that you know all terms, and that you automatically skip the first 5 steps which are soooo obvious.
Sounds manageable but I will only know the next time I end up on GitHub. Thank you for the help though, it might just be enough to get me through.
