+# cicd-pipeline-train-schedule-git
+
+This is a simple train schedule app written using nodejs. It is intended to be used as a sample application for a series of hands-on learning activities.
+
+## Running the app
+
+It is not necessary to run this app locally in order to complete the learning activities, but if you wish to do so you will need a local installation of npm. Begin by installing the npm dependencies with:
+
+    npm install
+
+Then, you can run the app with:
+
+    npm start
+
+Once it is running, you can access it in a browser at [http://localhost:3000](http://localhost:3000)
