1. [Install ruby](https://www.google.com/search?q=how+to+install+ruby),
2. run `$ bundle`,
3. run `$ bundle exec guard`,
4. have a fun!

In example I've used tmux notifications, they can be enabled by `$ cat ~/.guard.rb`:

``` ruby
notification :tmux, display_message: true
```

Guard also supports [growl, emacs etc](https://github.com/guard/guard#notification)
