-Note that [screenfull](https://github.com/sindresorhus/screenfull.js) is added as a bower dependency
-so if you use [main bower files](https://github.com/ck86/main-bower-files) the dependency will be added for you.
+You need to have both [screenfull](https://github.com/sindresorhus/screenfull.js) and angular-screenfull loaded in the browser in order to the directive to work. I have a an agular.js project using a custom loader, but if you want to add webpack support, PR's are welcomed.
