# j7s-branch-trigger

Occasionally checks the state of branches on a provided repo
using `git remote ls`.

If the "branches of concern" have updated since it last looked,
it will send a POST to a web hook.
The "branches of concern" are defined using a configured web hook.

Designed to replicate Jenkins Multibranch Pipeline triggers for
Tekton in a way that is git provider agnostic.
