Live update / hot reload / browser sync

You need Node.js for this. You can install BrowserSync using the command :

npm install -g browser-sync

Then browse to your project directory and open browsersync using :

browser-sync start --server --directory --files "*"

This will open a new tab in your browser which will list files in the directory, you can then select a html file to load and you should see a Connected to Browsersync message on the top right. This will also track changes in all files in your current directory and update the page whenever any file changes.
