+### Command Line
+
+Zanzibar comes bundled with the [`zamioculcas`](http://en.wikipedia.org/wiki/Zamioculcas) command-line utility that can be used for fetching passwords and downloading keys from outside of Ruby.
+
+`Zamioculcas` supports most actions provided by Zanzibar itself. Because it operates on the command-line, it can be used as part of a pipeline or within a bash script.
+
+```bash
+# if you don't pipe in a password, you will be prompted to enter one.
+# this will download the private key from secret 1984 to the current directory
+cat ./local-password | zamioculcas 1984 -s server.example.com -d example.com -t privatekey
+
+ssh user@someremote -i ./private_key
+```
