Does anyone have an example of how they implemented GitHub/Jenkins for environment promotion?

I attended the "Methodology and Strategy: Integrating DevOps with Appian to Deliver Software at the Speed of Business"  @AppianWorld18 and I asked at the conclusion of the session if they were going to share the jenkinsFile they used for creating the presentation. I do not wish to lose the momentum gained from my attending the session.  However, I would like to know how to hook up everything correctly, and I think a Jenkins file from either the presentation or someone else in the community would keep me pressing forward on my (and other community members) DevOps journeys.

Has anyone traveled down the automation path with Jenkins and GitHub and can they share either the Jenkinsfile / pipeline setup / or any other information that might be useful in automating my deployments?

Thanks,

Charles
