 **Overview**
 
-With the release of the 5 dollar PI Zero computer, there has never been a better time to start building a Docker Swarm. Whether you want to try distributed computing or just build something cool with your PI Zeros.
+With the release of the 5 dollar [Raspberry Pi Zero computer](https://shop.pimoroni.com/collections/raspberry-pi/products/raspberry-pi-zero), there has never been a better time to start building a Docker Swarm. Whether you want to try distributed computing or just build something cool with your Pi Zeros.
 
-In this quick-start guide we will configure Arch Linux ARM, install Docker and then use a laptop or another PC to create a swarm which all our PI Zeros can join. There are several ways of doing this, but we'll keep things simple and give you the opportunity to take it further later on. I've provided some sample images for Node.js, Redis, Ruby and Python so once you're up and running it's over to you to create something awesome.
+In this quick-start guide we will configure Arch Linux ARM or Raspbian, install Docker and then use a laptop or another PC to create a swarm which all our Pi Zeros can join. There are [several ways](https://docs.docker.com/swarm/discovery/) of doing this (called swarm discovery), but we'll keep things simple with a hard-coded list of swarm agents. You can take it further later on through the [Swarm Discovery documentation](https://docs.docker.com/swarm/discovery/). I've provided some [sample images](https://github.com/alexellis/docker-arm/tree/master/images/armv6) for Node.js, Redis, Ruby and Python so once you're up and running it's over to you to create something awesome.

 **Spreading images between the Swarm**
 
-The easiest way to spread your images between the Swarm is to push them to the Docker Hub with `docker push` then log into each PI and use `docker pull` to bring it into the local library. If you build an image pointing at the swarm manager then the manager will pick a random PI Zero to do the build.
