+Components
+==========
+
+This folder contains the WooCommerce-created components. These are exported onto a global, `wc.components`, for general use.
+
+## How to use:
+
+For any files not imported into `components/index.js` (`analytics/*`, `layout/*`, `dashboard/*`, etc), we can use `import { Card, etc … } from @woocommerce/components`.
+
+For any `component/*` files, we should import from component-specific paths, not from `component/index.js`, to prevent circular dependencies. See `components/card/index.js` for an example.
+
+```jsx
+import { Card, Link } from '@woocommerce/components';
+
+render: function() {
+  return (
+    <Card title="Card demo">
+      Card content with an <Link href="/">example link.</Link>
+    </Card>
+  );
+}
+```
+
+## For external development
+
+External developers will need to enqueue the components library, `wc-components`, and then can access them from the global.
+
+```jsx
+const { Card, Link } = wc.components;
+
+render: function() {
+  return (
+    <Card title="Card demo">
+      Card content with an <Link href="/">example link.</Link>
+    </Card>
+  );
