Salesforce Trailhead

Trailhead is the easiest—and most fun—way to learn Salesforce. With more than 30 trails made up of more than 100 modules, Trailhead allows you to learn the Lightning platform and other aspects of Salesforce at your own pace. Trailhead uses interactive challenges that you complete in your own Developer Edition org to test your skills at the end of each unit. When you complete modules, you earn badges that you can display proudly on your Salesforce Developers profile. Check out Trailhead at https://trailhead.salesforce.com.
