+## Usage and examples
+
+Here is a quick example to get you started, **it's all you need**:
+
+```jsx
+import * as React from "react";
+import ReactDOM from "react-dom";
+import { Dropzone, FileMosaic } from "@files-ui/react";
+Function App() {
+  const [files, setFiles] = React.useState([]);
+  const updateFiles = (incommingFiles) => {
+    setFiles(incommingFiles);
+  };
+  return (
+    <Dropzone onChange={updateFiles} value={files}>
+      {files.map((file) => (
+        <FileMosaic {...file} preview />
+      ))}
+    </Dropzone>
+  );
+}
+
+ReactDOM.render(<App />, document.querySelector("#app"));
+```
