[seriouspoop]

Is your feature request related to a problem? Please describe

I was struggling to find a example for using gocron-etcd-elector, never understood how to make it work with multiple instances of an application.

Describe the solution you'd like

I have written a new and better example which shows the use of replica instances and etcd cluster, and a live view of leader election in docker logs like in a production environment.

Describe alternatives you've considered
