I'm learning Node.js, my demo has two files: 

* `/server.js`
* `/public/index.html`

`/server.js` will get `/public/index.html` and then return to the client.

I'd like to use `nodemon` to auto reload when `/public/index.html` is modified. However, it seems like `nodemon` only works when I modify `/server.js` and not when `/public/index.html` is modified.

I'm using `nodemon server.js` to starting the server.
