 * Each container has a watchdog process that hosts a web server allowing a JSON post request to be forwarded to a desired process via STDIN. The respose is sent to the caller via STDOUT.
 * A gateway provides a view to the containers/functions to the public Internet and collects metrics for Prometheus and in a future version will manage replicas and scale as throughput increases.

 Check your `docker version` and upgrade to one of the latest 1.13-RCs from the [Docker Releases page](https://github.com/docker/docker/releases). This is already available through the Beta channel in Docker for Mac.
 
+## Quickstart with `docker stack deploy`
+
+For a complete stack of Prometheus, the gateway and the DockerHubStats function: 
+
+* Simply run `./deploy_stack.sh`.
+
+* Then head over to http://localhost:9090 for your Prometheus metrics
+
+* Your function can be accessed via the gateway like this:
+
+```
+# curl -X POST http://localhost:3000/function/func_hubstats -d "alexellis2"
+The organisation or user alexellis2 has 99 repositories on the Docker hub.
+
+# curl -X POST http://localhost:3000/function/func_hubstats -d "library"
+The organisation or user library has 128 repositories on the Docker hub.
+```
+
+The `-d` value passes in the argument for your function. This is read via STDIN and used to query the Docker Hub to see how many images you've created/pushed.
+
+If you're looking for a UI checkout the [Postman plugin for Chrome](https://www.getpostman.com) where you can send POSTs without needing `curl`.
+
+## Manual quickstart

 #### Create an attachable network for the gateway and functions to join
