A while ago, GitHub launched their Commit Status API which allows integrating the status of a build with commits and pull requests on GitHub. When a MyGet build source is linked to a GitHub repository and has credentials specified, we have started reporting status messages back to GitHub.
When a build succeeds or fails, you will see a status message posted to GitHub, linking to the build log on MyGet.
To enable GitHub Commit Status messages on your builds, make sure the build configuration has credentials specified. Specifying credentials can be done by removing and adding the build configuration again, a method which doesn’t require you to enter your password. You can also specify credentials manually by editing the build source.
