In order to enable LiveReload in your project you have to perform the following steps:
Open LiveReload and add the project folder to the ones LiveReload is listening to.
Add the following script to the HTML document you want to refresh each time a change is detected (you can get the script from the LiveReload user interface):
<script>document.write('<script src="http://' + (location.host || 'localhost').split(':')[0] + ':35729/livereload.js?snipver=1"></' + 'script>')</script>
Open the page in a web browser and connect it to LiveReload using the Chrome extension.
You just enabled the automatic refresh of the page you are working on each time a file in the specified folder is modified. Now you can save time when working with CSS and JavaScript!
