+# Docker Registry with Swarm superpowers
+
+To start your registry, just do:
+
+```
+docker-compose up -d
+```
+
+You can then refer to the registry as `localhost:5000`.
+
+If you are running on Swarm, do the following:
+
+```
+docker-compose up -d
+docker-compose scale frontend=N
+```
+
+... where `N` is the number of nodes in your cluster.
+
+This will make sure that a `frontend` container runs on every node,
+so that `localhost:5000` always refers to your registry.
+
+If you scale up your cluster, make sure to re-run `docker-compose scale`
+accordingly.
+
+If you supply a too large value for `N`, you will see errors
+(since Swarm tries to schedule more frontends than there are
+available hosts) but everything will work fine, don't worry.
+
+Note: this will bind port 5000 on the loopoback interface on
+all your machines. That port will therefore be unavailable if
+you try e.g. `docker run -p 5000:...`.
+
+Note: the registry will only be available from your cluster,
+through the loopback interface. If you want to make it available
+from outside, remove `127.0.0.1:` from the Compose file.
+
