Go to the "External" address specified by Browsersync in the terminal in the browser of your device.

gulp serve

gulp (build)

The default gulp command is set to creating a "dist" directory with a production version of the project, ready to be deployed. It minifies and renames js/css assets as well as cleaning the old "dist" directory. CSS is autoprefixed for the latest two browser versions.


gulp concatScripts

The gulp concatScripts command combines the specified js ressources into main.js. You can add new js files to this command on line 16 in gulpfile.js You might want to run concatScripts once seperately after adding new js files.
