Feel free to add common problems with their solutions here, or just anything that wasn't clear at first.

As seen in nodegit/#959 -- some golang hackers have started to use the following stanza in .gitconfig to allow go get to work with private repos:

[url "git@github.com:"]
        insteadOf = https://github.com/

But if you do this, code can call NodeGit.Clone.clone(url: 'https://foo') and have the authentication callback be asked for SSH credentials instead of HTTPS ones, which might not be what your application expected.
