+::: details Getting missing peer deps warnings?
+`@docsearch/js` has certain issues with its peer dependencies. If you see some commands failing due to them, you can try this workaround for now:
+
+On Yarn v2/v3, add this inside your rc file (`.yarnrc.yml` by default):
+
+```yaml
+packageExtensions:
+  '@docsearch/react@*':
+    peerDependenciesMeta:
+      '@types/react':
+        optional: true
+      'react':
+        optional: true
+      'react-dom':
+        optional: true
+```
+
+On PNPM, add this in your `package.json`:
+
+```json
+"pnpm": {
+  "peerDependencyRules": {
+    "ignoreMissing": [
+      "@types/react",
+      "react",
+      "react-dom"
+    ]
+  }
+}
+```
