+React-Native is better supported as of version `5.6.0`, using a specific build for the platform. The import should be automatic, but can be forced by importing from `/react-native` directly:
 
 ```typescript
 import { createClient } from "webdav/react-native";
 ```
 
+**NB:** Note that for some reason, the Metro build system doesn't properly resolve using these entries, and you may need to customise your babel config for React Native to correctly import this library:
+
+```javascript
+module.exports = {
+    presets: ["module:metro-react-native-babel-preset"],
+    plugins: [
+        [
+            "module-resolver",
+            {
+                alias: {
+                    // Point the webdav client entry to the react native build:
+                    webdav: "webdav/dist/react-native"
+                },
+                extensions: [".tsx", ".ts", ".js", ".jsx", ".json"]
+            }
+        ]
+    ]
+};
+```
+
+When using this override, you can simply import from `webdav`.

 ### Types
 
 Typescript types are exported with this library for the Node build. All of the types can also be directly imported from the module:
