+# building-a-multibranch-pipeline-project
+
+This repository is for the
+[Build a multibranch Pipeline project](https://jenkins.io/doc/tutorials/build-a-multibranch-pipeline-project/)
+tutorial in the [Jenkins User Documentation](https://jenkins.io/doc/).
+
+This tutorial uses the same application that the [Build a Node.js and React app
+with
+npm](https://jenkins.io/doc/tutorials/build-a-node-js-and-react-app-with-npm/)
+tutorial is based on. Therefore, you'll be building and testing the same
+application but this time, its delivery will be different depending on the Git
+branch that Jenkins builds from. That is, the branch being built determines
+which delivery stage of your Pipeline is executed.
+
+The `jenkins` directory contains an example of the `Jenkinsfile` (i.e. Pipeline)
+you'll be creating yourself during the tutorial and the `scripts` subdirectory
+contains shell scripts with commands that are executed when Jenkins processes
+either the "Deliver for development" or "Deploy for production" stages of your
+Pipeline (depending on the branch that Jenkins builds from).
