Just noticed in the readme:

> No need to first install the command on the other machine.

and

> It must be installed on your own machine and any machines that you'll be using to run commands. On those other machines you must make sure to install it globally, such that it can be started with a command like ssh user@host outrun.

Not sure if the readme is just out of date, or if I'm misunderstanding the initial statement about the _other machine_.
