-An easy to use Tweakpane/Leva-like library for React, built on top of
-Theatre.js.
+An easy to use [Tweakpane](https://cocopon.github.io/tweakpane/)/[Leva](https://github.com/pmndrs/leva)-like library for React, built on top of
+[Theatre.js](github.com/theatre-js/theatre).
 
-You can use Theatric to quickly tweak values in your React components, or create
-quick prototypes without worrying about setting up a UI.
+With Theatric you can:
 
-Unlike Leva or Tweakpane, Theatric can save or export the state of your controls
-and load it back in later. You can even share the state with other people, so
-they can see the same values you're seeing, or leave Theatric's `useControls`
-hooks in production, and let Theatric set the values from the provided state
-without displaying the UI.
+* Create controls for your React components.
+* Tweak those values while while your tweaks are persisted in the browser.
+* Undo/redo your tweaks, even after a page refresh.
+* Try out different assets (such as `.hdr` files), and once you're done, download your assets from the browser storage and put them in a static folder in your app.
 
-Since Theatric is built on top of Theatre.js, you can also animate all the
-values.
+## Quick start
 
-It comes with no peer-dependencies, all you need to do to set it up is run
-`yarn add theatric` or `npm install theatric`.
+```bash
+$ npm install theatric
+```
+
+```tsx
+// index.jsx
+import {initialize} from 'theatric'
+
+initialize().then(() => {
+  ReactDOM.render(<App />, document.getElementById('root'))
+})
+
+// App.jsx
+import {useControls} from 'theatric'
+import React from 'react'
+
+export default function App() {
+  const {name, age} = useControls({name: 'Andrew', age: 28})
+
+  return (
+    <div>
+      Hey, I'm {name} and I'm {age} years old.
+    </div>
+  )
+}
+```
+
+## Supported prop types
+
+Theatric supports all the prop types that Theatre.js supports. You can find a list of supported prop types [here](https://www.theatrejs.com/docs/latest/manual/prop-types).

 ### `initialize(config)`
 
 Optionally, you can call `initialize()` to initialize the UI with a certain
 state, or to take advantage of features like
-[assets](/docs/latest/manual/assets) support. `initialize()` takes the same
-config object as [`getProject`](/docs/latest/api/core#getproject_id-config_).
