Welcome to the source code repository for Salesforce Lightning Design System, brought to you by Salesforce UX.

SLDS is...

• Tailored for building Salesforce apps: Using the Lightning Design System markup and CSS framework results in UIs that reflect the Salesforce Lightning look and feel.
• Continuously updated: As long as you’re using the latest version of the Lightning Design System, your pages are always up to date with Salesforce UI changes.

This project utilizes Storybook for component development. If you would like to know more about Storybook or how it works, check out their website.

1. Clone the repository down locally.
2. cd into the project and run npm install to install all project dependencies.

If you've just installed the project, you will need to run npm run full-start to first perform a full build, which is necessary for Storybook to operate.

Whenever you add or remove a component, you'll want to perform this full-start. Otherwise, you can just run npm start to start the Storybook server without a build.

Once the development server is started with npm start, you can load it at http://localhost:9002.

See the annotations guide.

Starts the Storybook server for local development.

Performs a full build and dist before starting the Storybook server. Useful for when a component or utility is added or removed from the system.
