+# Dockerized Version
+
+WeTTY can be run from a container to ssh to a remote host or the host system.
+This is handy for quick deployments. Just modify `docker-compose.yml` for your
+host and run:
+
+```sh
+$ docker-compose up -d
+```
+
+This will start 2 containers, one will be WeTTY container running ssh client the
+other will be a container running ssh server.
+
+Visit the appropriate URL in your browser
+(`[localhost|$(boot2docker ip)]:PORT`).
+
+The default username is `term` and the password is `term`, if you did not modify
+`SSHHOST`
+
+In the docker version all flags can be accessed as environment variables such as
+`SSHHOST` or `SSHPORT`.
+
+If you don't want to build the image yourself just remove the line `build; .`
+
+If you wish to use the WeTTY container in prod just modify the WeTTY container
+to have `SSHHOST` point to the server you want to ssh to and remove the ssh
+server container.
