+
+#### Error: callback returned unsupported credentials type ####
+
+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 "[email protected]:"]
+        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.
