Project Setup

Salesforce DX introduces a new project structure for your org’s metadata (code and configuration), your org templates, your sample data, and all your team’s tests. Store these items in a version control system (VCS) to bring consistency to your team’s development processes. Retrieve the contents of your team’s repository when you’re ready to develop a new feature.

You can use your preferred VCS. Most of our examples use Git.

You have different options to create a Salesforce DX project depending on how you want to begin.
