In this module, you create a Developer Edition Account that provides you with a full-featured but isolated Salesforce environment to perform the exercises in this workshop. You then enable Lightning Components in that development environment.
Even if you already signed up for a Developer Edition account, it is strongly recommended that you sign up for a new Developer Edition account for this tutorial.
