+## Running Mimic on Docker ##
+
+The repository root has a `Dockerfile` that does what you want. It exposes Mimic on port 8900 by default.
+
+To play around with Mimic locally, try:
+
+```
+docker build -t mimic . && docker run --restart=no --rm=true -p 8900:8900 mimic
+```
+
+This will expose Mimic on port 8900, so you can access it directly from the host. The default port exposure is intended for communication between containers; see the Docker documentation for more information. If you're using `boot2docker`, run `boot2docker ip` to find the right IP.
