+Once you have added the Docker repo to `/etc/apt/sources.list.d/`, you should
+see `docker.list` if you:
+
+```bash
+$ ls /etc/apt/sources.list.d/
+```
+
+And the contents of the `docker.list` should read:
+
+`deb [arch=armhf] https://apt.dockerproject.org/repo raspbian-jessie main`
+
+If you don't see that in `docker.list`, then either comment the line out, or
+`rm` the `docker.list` file.

+Once you have verified that you have the correct repository, you may continue

+
+    Use this command to install the latest version of Docker:
+

+    image.
+
+    ```bash
+    $ sudo docker run hypriot/armhf-hello-world

+
+    This command downloads a test image and runs it in a container. When the
