+# Dev server polyfill
+
+Plugin to load polyfills during development. Uses [`@web/polyfills-loader`](https://modern-web.dev/docs/building/polyfills-loader/) internally.
+
+## Usage
+
+`web-dev-server.config.js`:
+
+```js
+import { polyfill } from '@web/dev-server-polyfill';
+
+export default {
+  plugins: [
+    polyfill({
+      scopedCustomElementRegistry: true,
+    }),
+  ],
+};
+```
+
+You can find the supported polyfills [here](https://modern-web.dev/docs/building/polyfills-loader/#polyfills).
+
+You can also provide custom polyfills:
+
+`web-dev-server.config.js`:
+
+```js
+import { polyfill } from '@web/dev-server-polyfill';
+
+export default {
+  plugins: [
+    polyfill({
+      custom: [
+        {
+          name: 'my-feature-polyfill',
+          path: 'path/to/my/polyfill.js',
+          test: "!('myFeature' in window)",
+        },
+      ],
+    }),
+  ],
+};
+```
+
+You can find the configuration options for providing custom polyfills [here](https://modern-web.dev/docs/building/polyfills-loader/#custom-polyfills).
