+#### Joyent Triton
+
+Create machines on [Joyent's Triton](http://joyent.com/) Elastic Container Infrastructure.
+
+Before using the Docker service on Triton, you need to have completed the signup
+process and generated a set of SSH keys (make sure you know the name and
+location of your SSH key). Please visit
+[getting started](https://www.joyent.com/developers/getting-started) for more
+information.
+
+If you want to try to run Joyent's SDC on your laptop please visit [the getting
+started with Cloud on a Laptop section](https://github.com/joyent/sdc#getting-started)
+or if you already are running SmartDataCenter [here](https://github.com/joyent/sdc-docker)
+is what you need to do in order to enable the Docker service:
+
+        $ docker-machine create --driver triton --triton-url=$CLOUDAPI_URL --triton-account=$ACCOUNT --triton-key=$PATH_TO_PRIVATE_SSH_KEY
+
+Options:
+
+ - `--triton-url`     : The Triton Cloudapi URL (e.g. https://us-east-3b.api.joyent.com).
+ - `--triton-account` : The Triton acount name (e.g. jill).
+ - `--triton-key`     : The path to your private key file (e.g. ~/.ssh/id_rsa).
+
+The first thing that will happen when you run `$ docker-machine create --driver
+triton` is that your private key will be used for generating a certificate that
+the Docker client can then use to communicate securely with the Triton docker
+service.
+
+Note that some docker-machine commands are not supported in Triton (e.g. ssh,
+start, stop, upgrade) as Triton provides a dynamic and flexible docker cloud
+environment, and so the provisioning of individual machines isn't necessary.
