+## Getting Started
 
 ### Creating a new app with the SDK (NPM)
 
 #### Set up an application on Stitch
+
+First, you need to create the server-side Stitch app, and (for the purpose of this quick start) enable anonymous authentication:
+
 1. Go to [https://stitch.mongodb.com/](https://stitch.mongodb.com/) and log in to MongoDB Atlas.
 2. Create a new app in your project with your desired name.
 3. Go to your app in Stitch via Atlas by clicking Stitch Apps in the left side pane and clicking your app.
 3. Copy your app's client app id by going to Clients on the left side pane and clicking copy on the App ID section.
 4. Go to Providers from Users in the left side pane and edit and enable "Allow users to log in anonymously".
 
+For detailed instructions, see [Create a Stitch App](https://docs.mongodb.com/stitch/procedures/create-stitch-app/).
+
 #### Set up an NPM project
+
+Next, you create the source for your client app.
+
 1. Ensure that you have `npm` installed. See [npmjs.com](https://www.npmjs.com).

+
+#### Executing a Stitch Function
+
+One of Stitch's powerful features is serverless [Functions](https://docs.mongodb.com/stitch/functions/). Once logged in, the Stitch client can execute remote Stitch Functions using the [StitchAppClient.callFunction](interfaces/stitchappclient.html#callfunction) method:
+
+```javascript
+client.callFunction("echoArg", ["Hello world!"]).then(echoedResult => {
+  console.log(`Echoed result: ${echoedResult}`);
+})
+```
 
-This library depends on [js-bson](https://www.npmjs.com/package/js-bson).
+Assuming you've configured your Stitch application to have a function named "echoArg" that returns its argument, you should see a message like:
+
+```
+Echoed result: Hello world!
+```
+
+The `echoArg` Function in Stitch would look something like:
+
+```javascript
+// echoArg Function in the Stitch UI
+exports = function(arg) {
+  return {arg: arg};
+};
+```
