+## My PR is broken, it works in VS!
+
+if your pull request is broken either one of two things is happening.
+
+1. Your changes are not mono compatible, which prevent linux users from using your changes. This will only happen if travis ci says your build is broken, but appveyor does not.
+2. You have added gendarme violations. You can run gendarme locally by running `rake preflight` from your console.
