+# Contributions to concourse/concourse

+Concourse is a container-based automation system written in Go. It's mostly used for CI/CD.

+This repository holds only my commits to the upstream project, with their original author, date and diff.
+Each of my commits is preceded by a snapshot of the upstream files it touched, so every diff shows exactly what I changed.
