+# Tekton cli Repo CI/CD
+
+We dogfood our project by using Tekton Pipelines to build, test and
+release the Tekton Pipelines cli!
+
+This directory contains the
+[`Tasks`](https://github.com/tektoncd/pipeline/blob/master/docs/tasks.md) and
+[`Pipelines`](https://github.com/tektoncd/pipeline/blob/master/docs/pipelines.md)
+that we (will) use for the release and the pull-requests.
+
+TODO(tektoncd/pipeline#538): In tektoncd/pipeline#538 or tektoncd/pipeline#537 we will update
+[Prow](https://github.com/tektoncd/pipeline/blob/master/CONTRIBUTING.md#pull-request-process)
+to invoke these `Pipelines` automatically, but for now we will have to invoke
+them manually.
+
+## Release Pipeline
+
+The release pipeline uses the
+[`golang`](https://github.com/tektoncd/catalog/tree/master/golang)
+Tasks from the
+[`tektoncd/catalog`](https://github.com/tektoncd/catalog). To add them
+to your cluster:
+
+```
+kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/master/golang/lint.yaml
+kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/master/golang/build.yaml
+kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/master/golang/tests.yaml
+```
+
+It also uses the [`goreleaser`](./goreleaser.yml) Task from this
+repository.
+
+```
+kubectl apply -f ./goreleaser.yml
+```
+
+Next is the actual release pipeline. It is defined in
+[`release-pipeline.yml`](./release-pipeline.yml).
+
+```
+kubectl apply -f ./release-pipeline.yml
+```
+
+Note that the [`goreleaser.yml`](./goreleaser.yml) `Task` needs a
+secret for the GitHub token, named `bot-token-github`.
+
+TODO(vdemeester): It is hardcoded for now as Tekton Pipeline doesn't
+support variable interpolation in the environment. This needs to be
+fixed upstream.
+
+```
+kubectl create secret generic bot-token-github --from-literal=bot-token=${GITHUB_TOKEN}
+```
+
+
+### Running
+
+To run these `Pipelines` and `Tasks`, you must have Tekton Pipelines installed
+(in your own kubernetes cluster) either via
+[an official release](https://github.com/tektoncd/pipeline/blob/master/docs/install.md)
+or
+[from `HEAD`](https://github.com/tektoncd/pipeline/blob/master/DEVELOPMENT.md#install-pipeline).
+
+- [`release-pipeline-run.yml`](./release-pipeline-run.yml) — this
+  runs the `ci-release-pipeline` on `tektoncd/cli` master branch. The
+  way [`goreleaser`](https://goreleaser.com) works, it will build the
+  latest tag.
