Choosing Your Development Environment
To follow along with the exercises in this book, you’ll need a Salesforce account. If you’re a Salesforce customer, you can use a Lightning Platform sandbox. A sandbox is a copy of your Salesforce org that you can use for testing configurations and training users without compromising the data in your production org. Professional, Enterprise, Unlimited, and Performance Editions come with free sandboxes. Users of other editions can use Developer Edition to do the exercises.
If you’re new to Salesforce, or if you don’t want to use a sandbox, go to http://sforce.co/WBtUN7 and sign up for a free Developer
Edition account. Developer Edition is a fully functional version of
Salesforce that you can use to develop Salesforce apps. Since it’s free, there are limits on the
amount of users, bandwidth, and storage you’re allowed, but it includes all the features in
Salesforce. When you sign up, you become part of the growing community of Lightning
platform developers around the world.
