+# Container Images
+
+In this directory we've put together several different Dockerfile's that can be used to build
+containers that have coach and other environments/dependencies installed.  How to build these
+and what each contains is defined below:
+
+## default `Dockerfile`
+* `make build` to create the image
+* will create a basic Coach installation along with Gym (atari), Mujoco, and Vizdoom environments.
+* useful for running unit/integration tests  `make unit_tests` to run these in the container
+* `make shell` will launch this container locally, and provide a bash shell prompt.
+* includes GPU support (derives from `Dockerfile.base` which is a CUDA ubuntu 16.04 derived image)
+
+## `Dockerfile.mujoco_environment`
+* `docker build --build-arg MUJOCO_KEY=${MUJOCO_KEY} -f docker/Dockerfile.mujoco_environment .`
+  from the parent dir to create the image
+* contains mujoco environment and Coach.
+* you need to supply your own license key (base64 encrypted) as an environment variable `MUJOCO_KEY`
+  to ensure you get the complete Mujoco environment
+
+## `Dockerfile.gym_environment`
+* `docker build -f docker/Dockerfile.gym_environment .` from the parent dir to create the image
+* contains OpenAI Gym environment (and all extras) and Coach.
+
+## `Dockerfile.doom_environment`
+* `docker build -f docker/Dockerfile.doom_environment .` from the parent dir to create the image
+* contains vizdoom environment and Coach.
