+# About
+
+This directory contains code to build a docker nmag container based on Ubuntu 12.04.
+
+# Dependencies
+
+* [Docker](https://docs.docker.com/install/)
+
+# Building
+
+In order to build the container run `docker build -t nmag .` from the current directory
+
+# Using
+
+You can start the nmag environment using `docker run -it nmag`.
+To give the nmag environment access to the current directory and its children, use the format `docker run -it -v $PWD:/mnt nmag`.
+
+# Testing
+
+Use the sphere1 simulation included in the current directory to test the container like so:
+```
+docker run -it -v $PWD:/mnt nmag
+$ nsim sphere1.py
+```
