Go Caveats

I don’t particularly love that this isn’t the cleanest set of warnings in the world, but the combination of Homebrew, zsh & Go seems to really screw up the setting of the GOPATH & the $PATH as recommended. (*The problem seems to replicate across any non-default shell*). I’ve chucked in a few lines consequently about how to handle non-default shells.

I’ll respect if this somewhat cumbersome explanation is rejected, but hopefully it’s useful to include.
Aye. I just wondered whether it was worth chucking in a notation about that behaviour, given Go tells people to use the ``` export ``` command to set the GOPATH. I'll happily bow to your knowledge on this front though, If you feel like it isn't necessary that's all cool with me.
