These are *appended* to the node-livereload upstream defaults which ignore everything in the `.git/`, `.svn/` and `.hg/` directories.<br />JavaScript regex format is: `/your-regex/`<br />**N.B.** At present, exclusions do not seem to be working properly.

 - `listen`: start the Livereload server
 
+> Depending on your environment, you may *not* want to expose your Livereload server on all interfaces! You may want to map your port to something like `127.0.0.1:35729:35729` and then establishing an SSH-tunnel from your client. This is completely dependent on your environment and beyond the scope of this readme, sorry.
