	fmt.Println("PID:", os.Getpid())

	// Create a new thread to listen signals received by operation system
	go ossignals.On(

		// Create actions to each signal
		ossignals.Actions{
			syscall.SIGTERM: func() bool {
				fmt.Println("I'm dying...")
				return true
			},
			syscall.SIGHUP: func() bool {
				// Here we can do reload a config, reload connections, or anything...

				return true
			},

}

Case you don't know about signals in the operating system you can read this doc.
