 # @strudel.cycles/react

-This package contains react hooks and components for strudel.
-Example coming soon
+This package contains react hooks and components for strudel. It is used internally by the Strudel REPL.
+
+## Install
+
+```js
+npm i @strudel.cycles/react
+```
+
+## Usage
+
+Here is a minimal example of how to set up a MiniRepl:
+
+```jsx
+import { evalScope, controls } from '@strudel.cycles/core';
+import { MiniRepl } from '@strudel.cycles/react';
+import { prebake } from '../repl/src/prebake.mjs';
+
+evalScope(
+  controls,
+  import('@strudel.cycles/core'),
+  import('@strudel.cycles/tonal'),
+  import('@strudel.cycles/mini'),
+  import('@strudel.cycles/webaudio'),
+  /* probably import other strudel packages */
+);
+
+prebake();
+
+export function Repl({ tune }) {
+  return <MiniRepl tune={tune} hideOutsideView={true} />;
+}
+```
+
+## Development
+
+If you change something in here and want to see the changes in the repl, make sure to run `npm run build` inside this folder!
+
+```js
+npm run dev # dev server
+npm run build # build package
+```
