/**
 * PingOne Integration Guide - Express.js Sample App
 *
 * This repo
 * (https://github.com/dbrowski/pingone-express_js-sample-app-guide#readme) is
 * designed as a guide that walks you through the steps to add authentication
 * using PingOne into a traditional web app. Running the app at any step will
 * spin up an Express server which will serve a minimal UI. You can use this to
 * trigger a PingOne Authentication or DaVinci Policy assigned to a PingOne App
 * Connection.
 *
 * This step sets up starting point, a simple web app. The code comes from the
 * Hello world example from Express.
 * https://expressjs.com/en/starter/hello-world.html
