+feat(ui): experimental component theming
+
+This feature lets you fully style and theme built-in components even if there is no design token available. For example, previously you could not add a box shadow or gradient background to the built-in Button component unless you wrote plain CSS. Now you can style every CSS property for all the built-in components with type-safety!
+
+This also lets you define your own components and style them in the same type-safe way with zero runtime computation.
+
+### defineComponentTheme()
+
+```ts
+import { defineComponentTheme } from '@aws-amplify/ui-react/server';
+
+export const buttonTheme = defineComponentTheme({
+  // because 'button' is a built-in component, we get type-safety and hints
+  // based on the theme shape of our button
+  name: 'button',
+  theme: (tokens) => {
+    return {
+      textAlign: 'center',
+      padding: tokens.space.xl,
+      _modifiers: {
+        primary: {
+          backgroundColor: tokens.colors.primary[20],
+        },
+      },
+    };
+  },
+});
+```
+
+
+### createTheme() 
+
+The theme object passed to `createTheme` now has an optional `components` array which is an array of component themes. 
+
+```ts
+export const theme = createTheme({
+  name: 'my-theme',
+  components: [
+    buttonTheme,
+    customComponentTheme,
+  ]
+})
+```
+
+### <Theme /> RSC
+
+```tsx
+import { Theme } from '@aws-amplify/ui-react/server';
+import { theme } from '@/theme';
+
+export default function RootLayout({
+  children,
+}: {
+  children: React.ReactNode;
+}) {
+  return (
+    <Theme theme={theme} colorMode="system">
+      {children}
+    </Theme>
+  )
+}
