#### What are you trying to achieve or the steps to reproduce?

Vision's package.json's `repository` field is apparently incorrect. It says `git://github.com/hapijs/vision`; however, as far as I know, GitHub doesn't support the `git://` URL scheme. Instead, it should be https://github.com/hapijs/vision.git.

#### What was the result you got?

Non-functioning repository
