More details - http://blog.gbaman.info/?p=791

For this method, alongside your Pi Zero, MicroUSB cable and MicroSD card, only an additional computer is required, which can be running Windows (with Bonjour, iTunes or Quicktime installed), Mac OS or Linux (with Avahi Daemon installed, for example Ubuntu has it built in).

	has many issues which are fixed by this tools:
	* If your editor creates a backup before writing the file, it'll trigger multiple times.
	* If your directory structure is deep, it'll have to reinitialize inotify after each change.
