+# M3DB Docker build processes
+
+## Development building and testing 
+
+The `Dockerfile-dev` file is intented to help bootstrap the development
+process by providing a simple Dockerfile to perform the build process within 
+a container namespace. Docker's container runtime also provides simple way to
+simulate production like environment. 
+
+```
+docker build -t m3dbnode:latest -f Dockerfile-dev . 
+docker run --name m3dbnode m3dbnode:latest 
+```
+
+## Production building and release 
+
+The `Dockerfile-release` file is intented to provide the Docker image used within a 
+production environment in which the minimal amount of artifacts are placed
+within the container.
+
+```
+docker build -t m3dbnode:$(git rev-parse head) -f Dockerfile-release . 
+docker run --name m3dbnode m3dbnode:$(git rev-parse head)
+```
