-## Sozuctl
-
-Sozuctl is a command line interface for the proxy. You can send configuration orders (e.g. Add a new worker) or reclaim some metrics at the proxy with this executable. Sozuctl talks to the proxy through a unix socket.
-
-You can specify its path by adding to your `config.toml`:
-
-``` toml
-command_socket = "path/to/your/command_folder/sock"
-```
-
 ## Metrics
 
 Sōzu reports its own state to another network component through a `UDP` socket. The master and the workers are responsible to send their states. We implement the [statsd](https://github.com/b/statsd_spec) protocol to send the statistics.

-`sozuctl` has a few commands you can use to interact with the reverse proxy:
-
-- soft shutdown (wait for active connections to stop): `sozuctl -c config.toml shutdown`
-- hard shutdown: `sozuctl -c config.toml shutdown --hard`
-- display the list of current configuration messages: `sozuctl -c config.toml state dump`
-- save the configuration state to a file: `sozuctl -c config.toml state save -f state.json`
