+# docker
+
+This is the docker daemon system container for Fedora systems based on the moby project.
+For more information refer to: https://github.com/moby/moby
+
+Note this only provides the *daemon process*, and does not include CLI tools. The current use
+case for this would be switching between different versions of docker by updating the container.
+
+## Building the image from source:
+
+```
+# git clone https://github.com/projectatomic/atomic-system-containers
+# cd atomic-system-containers/docker-fedora
+# docker build -t docker .
+```
+
+## Running the system container, with the atomic CLI:
+
+Pull from registry into ostree:
+
+```
+# atomic pull --storage ostree $REGISTRY/docker
+```
+
+Or alternatively, pull from local docker:
+
+```
+# atomic pull --storage ostree docker:docker:latest
+```
+
+Install the container:
+
+Currently we recommend using --system-package=no to avoid having rpmbuild create an rpm file
+during installation. This flag will tell the atomic CLI to fall back to copying files to the
+host instead.
+
+```
+# atomic install --system --system-package=no --name=docker ($REGISTRY)/docker
+
+Note that if you have the package docker locally, you would need to use another
+name for the service (i.e. --name=docker-system-container, etc.)
+```
+
+Start as a systemd service:
+
+```
+# systemctl start docker
+```
+
+Stopping the service
+
+```
+# systemctl stop docker
+```
+
+Removing the container
+
+```
+# atomic uninstall docker
+```
