 The pull_request object contains all the metadata github returns for a pull request as defined [here](http://developer.github.com/v3/pulls/#get-a-single-pull-request)
+
 Comments is an array of comments on that pull request as defined [here](http://developer.github.com/v3/issues/comments/#list-comments-on-an-issue)
+
 Next is the callback function you should run when your check is complete. If you return no parameter, GitEnforcer will continue execution on the next middleware. If you specify a paramater (as a string) then execution of middleware stops, and that string is set as the reason for failure on the pull request's status.
