 # Overview
 
-To give this a try:
+Promenade is tool for deploying self-hosted Kubernetes clusters using
+[bootkube](https://github.com/kubernetes-incubator/bootkube).
 
-```
-make save
+## Quickstart using Vagrant
+
+Make sure you have [Vagrant](https://vagrantup.com) and
+[VirtualBox](https://www.virtualbox.org/wiki/Downloads) installed.  Then
+install the `vagrant-hostmanager` plugin.
+
+```bash
 vagrant plugin install vagrant-hostmanager
+```
 
+Build the genesis and join images and save them to disk for quick loading into
+the Vagrant VMs.
+
+```bash
+make save
+```
+
+Start the VMs and save a snapshot for quicker iteration:
+
+```bash
+vagrant up
+vagrant snapshot save clean
+```
+
+Spin up a cluster:
+
+```bash
 ./test-install.sh
 ```
+
+Watch nodes spin up:
+
+```bash
+watch kubectl --insecure-skip-tls-verify --kubeconfig <(sed 's/kubernetes:443/192.168.77.10:443/' < assets/kubeconfig) get nodes
+```
+
+To test changes, you can safely reset single or multiple nodes:
+
+```bash
+vagrant snapshot resotre n2 clean
+vagrant snapshot restore clean
+```
+
+## Detailed Deployment
+
+The basic outline for deploying a cluster is:
+
+1. Overwrite the placeholder assets in the `assets` directory.
+2. Make sure the `Makefile` lists the images and versions you expect to be
+   required.
+3. Build the images with `make build`
+4. Setup each host with the following:
+   - DNS resolution pointing `kubernetes` to the appropriate IPs for the
+     Kubernetes API
+   - A running docker daemon, configured to use the DNS resolution specified
+     above (see `vagrant-assets/docker-daemon.json`)
+5. Transfer the appropriate images to each host.  You may find it useful to
+   run `make save`, transfer the image and then use `docker load -i ...` to
+   restore it rather than to rely on a registry.
+6. On the genesis (seed) server, start the cluster:
+   `docker run --rm -v /:/target -v /var/run/docker.sock:/var/run/docker.sock -e NODE_HOSTNAME=genesis-node.fqdn quay.io/attcomdev/promenade-genesis:dev`
+7. On each additional node:
+   `docker run --rm -v /:/target -v /var/run/docker.sock:/var/run/docker.osck -e NODE_HOSTNAME=join-node.fqdn quay.io/attcomdev/promenade-join:dev`
