Giving a basic Magento 2 front-end training for a group of professional front-end developers. Learning them about the ins and outs of Magento 2 theming, the Magento 2 folder structure, how to setup a custom theme, grunt setup, LESS compilation, requirejs, jquery UI widget factory, knockoutjs basics, developer mode, production mode, deployment methods and common pittfalls. They realized Magento 2 theming has a steep learning curve, and requires more than just regular front-end skills but where enthusiastic and willing to give it a go by the end of the course.
