+If you have an AWS account and have already installed and configured the AWS CLI tool, you can easily deploy this application to API Gateway and Lambda via CloudFormation in a few minutes.
+
+Instead of editing `config.js`, take these steps:
+
+1. Copy `aws/config.example.sh` to `aws/config.sh`
+2. Edit the values in `aws/config.sh`, which correspond to the variables described above, plus these:
+    * `StackName`: the name of the CloudFormation stack to create
+    * `S3BucketArtifacts`: the name of an existing S3 bucket you have write access to, for storing deployment artifacts
+    * `S3PrefixArtifacts`: the prefix to use within that S3 bucket for all deployment artifacts written
+3. Run `aws/deploy.sh` to create the CloudFormation stack and deploy your application, outputting the URL
+4. (Optional) For a friendlier URL, log into the AWS web console and establish a custom domain pointing to the API Gateway stage deployed in step 3.
+
 ## Run
 [Node.js](http://nodejs.org/) is required.
