 The main changes are that the SDK now relies on the [builtin Web fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) instead of `node-fetch` and has zero dependencies.
 
+## Migration CLI
+
+Most programs will only need minimal changes, but to assist there is a migration tool that will automatically update your code for the new version.
+To use it, upgrade the `@anthropic-ai/sdk` package, then run `./node_modules/.bin/anthropic-ai-sdk migrate ./your/src/folders` to update your code.
+To preview the changes without writing them to disk, run the tool with `--dry`.
+
 ## Environment requirements
 
 The minimum supported runtime and tooling versions are now:
 
-- Node.js 18.x last LTS (Required for built-in fetch support)
+- Node.js 18.x last LTS (Required for builtin fetch support)
   - This was previously documented as the minimum supported Node.js version but Node.js 16.x mostly worked at runtime; now it will not.

 - Jest 28

+Because we now use the builtin Web fetch API on all platforms, if you wrote code that used `withResponse` or `asResponse` and then accessed `node-fetch`-specific properties on the result, you will need to switch to standardized alternatives.
+For example, `body` is now a [Web `ReadableStream`](https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream) rather than a [node `Readable`](https://nodejs.org/api/stream.html#readable-streams).

+res.body.pipe(process.stdout);

+// After:
+import { Readable } from 'node:stream';
+const res = await client.example.retrieve('string/with/slash').asResponse();
+Readable.fromWeb(res.body).pipe(process.stdout);

+When referencing the library after updating, you may encounter new type errors related to JS features like private properties or fetch classes like Request, Response, and Headers.
+To resolve these issues, configure your tsconfig.json and install the appropriate `@types` packages for your runtime environment using the guidelines below:
