This repo contains code structured as sfdx projects. However, you don't have to use SFDX in order to access these components. Each component has its own folder inside force_app/main/default/aura, and you can simply copy and paste the component files to your development environment and deploy your usual way. That said, we recommend you give SFDX a try. It makes deployment of components like these a matter of a few command line keystrokes, and we think it's wonderful. Also, it's free. Learn more at:
