+## V2 Migration Guide
+
+> The SDK was rewritten in V2 and is now programatically generated from our OpenAPI spec. As part of this release there are some breaking changes.
+
+#### Client Instantiation
+The SDK exports `WebflowClient` instead of `Webflow`. The client now takes `accessToken` instead of `token`. 
+
+```ts
+const webflow = new WebflowClient({ accessToken: "..." }); 
+```
+
+#### Oauth 
+The `WebflowClient` exports static methods that you can use for OAuth. These were previously on `Webflow`. 
+
+`webflow.authorizeUrl` -> `WebflowClient.authorizeURL`
+
+`webflow.accessToken` -> `WebflowClient.getAccessToken`
+
+`webflow.revokeToken` -> `WebflowClient.revokeToken`
+
+#### HTTP Client
+The SDK no longer uses Axios and defaults to fetch. The SDK supports multiple runtimes and will handle
+using a fetch implementation if available or will default to `node-fetch`. 
+
+### Resources
+Previously the SDK only supported the most important resources, such as site and user. Now the SDK supports
+methods on a variety of different endpoints such as `collections`, `assets`, `forms`, `inventory`, `orders`, etc.
