 #### Docker
 This repository contains a `Dockerfile` allowing you to build and run the server as a [docker](https://www.docker.com/) container.
 
-To get started issue `docker build -t cwtch:latest`, this will create 2 temporary docker containers, one to build the Tor daemon and one to build Cwtch. The compiled binaries will then be bundled into a new image and tagged as `cwtch:latest`.
+To get started issue `docker build -t openpriv/cwtch-server:latest`, this will create 2 temporary docker containers, one to build the Tor daemon and one to build Cwtch. The compiled binaries will then be bundled into a new image and tagged as `openpriv/cwtch-server:latest`.
 
-To run Cwtch in the foreground execute `docker run cwtch:latest`, you will see a small amount of output from Tor and then Cwtch will output your server address. When you `Ctrl + C` the container will terminate. To run Cwtch in the background execute `docker run --name my-cwtch-server -d cwtch:latest`. To get your Cwtch server address issue `docker logs my-cwtch-server`.

+The image creates 3 volumes, for /etc/cwtch, /etc/tor, /var/lib/tor

+##### Upgrading
+
+To upgrade with continuity
+
+```
+# Stop current container/service
+docker stop my-cwtch-server
+
+docker pull openpriv/cwtch-server
+
+# Create a new container and copy the volumes (cwtch/onion keys, message store)
+docker create --name my-cwtch-server-2 --volumes-from my-cwtch-server openpriv/cwtch-server:latest
+
+# Resume service with the new container
+docker start my-cwtch-server-2
