+## Quick Example for a NodeJS Function (4 minutes)
+
+This example will show you how to test and deploy a Node function to Oracle Functions.
+
+```sh
+# create your func.yaml file
+fn init <YOUR_DOCKERHUB_USERNAME>/hello
+# build the function
+fn build
+# test it
+cat hello.payload.json | fn run
+# push it to Docker Hub
+fn push
+# Create a route to this function on Oracle Functions
+fn routes create myapp /hello
+```
+
+Now surf to: http://localhost:8080/r/myapp/hello
+
+## Dependencies
+
+Create a [package.json](https://docs.npmjs.com/getting-started/using-a-package.json) file in your functions directory.
+
+Run:
+
+```sh
+docker run --rm -v "$PWD":/function -w /function funcy/node:dev npm install
+```
+
+Then everything should work.
+
+For example, using the `package.json` file in this directory which includes the [request](https://www.npmjs.com/package/request) package, you can add this to func.js and it will work:
+
+```js
+var request = require('request');
+request('http://www.google.com', function (error, response, body) {
+  if (!error && response.statusCode == 200) {
+    console.log(body) // Show the HTML for the Google homepage.
+  }
+})
+```
