I have been using vim for a while now and decided to try Emacs. I picked Spacemacs since it's easier for a vim user to transition to.
I was able to create a package layer to install packages hosted in MELPA but when I tried installing packages hosted on GitHub using :fetcher github
it gave an error: 'Package [package name] is unavailable. Is the package name misspelled?'
A few packages I tried are Emacs Webkit and haxe-complete
How do I install packages hosted on GitHub?
Edit: I forgot to mention I've checked out the develop branch.
