+# Overview
+
+Docker allows you to quickly spin up containers.  The ZoneMinder dockerfile will spin
+up an Ubuntu 12.04 container with mysql, apache, php and then compile and install ZoneMinder (from master).
+
+Afterwards you can connect to this container over SSH to check out the latest code.
+
+This is still a bit of a work in progress.
+
+## How To Use
+
+1. Pull it
+```sudo docker pull ubuntu:precise```
+2. Built it
+```sudo docker build -t yourname/zoneminder github.com/ZoneMinder/ZoneMinder```
+3. Run it
+```CID=$(sudo docker run -d -p 222:22 -p 8080:80 -name zoneminder yourname/zoneminder)```
+4. Use it -- you can now SSH to port 222 on your host as user root with password root.
+You can also browse to your host on port 8080 to access the zoneminder web interface
