+## React Native
+
+To be able to use `@uploadcare/upload-client` with React Native, you need to
+install [react-native-url-polyfill][react-native-url-polyfill].
+
+To prevent [`Error: Cannot create URL for blob`][react-native-url-polyfill-issue]
+errors you need to configure your Android app schema to accept blobs -
+have a look at this pull request for an example: [5985d7e][react-native-url-polyfill-example].
+
+You can use `ReactNativeAsset` as an input to the `@uploadcare/upload-client` like this:
+
+```ts
+type ReactNativeAsset = {
+  uri: string
+  type: string
+  name?: string
+}
+```
+
+```ts
+const asset = { uri: 'URI_TO_FILE', name: 'file.txt', type: 'text/plain' }
+uploadFile(asset, { publicKey: 'YOUR_PUBLIC_KEY' })
+```
+
+Or `Blob` like this:
+
+```ts
+const uri = 'URI_TO_FILE'
+const blob = await fetch(uri).then((res) => res.blob())
+uploadFile(blob, { publicKey: 'YOUR_PUBLIC_KEY' })
+```
