@@ -10,5 +10,6 @@ Qwik City comes pre-bundle with:
 - generic [`requestHandler()`](https://github.com/BuilderIO/qwik/blob/main/packages/qwik-city/middleware/request-handler/) function.
 - [`express`](https://github.com/BuilderIO/qwik/tree/main/packages/qwik-city/middleware/express) middleware
 - [`cloudflare-pages`](https://github.com/BuilderIO/qwik/tree/main/packages/qwik-city/middleware/cloudflare-pages) middleware
+- [`netlify`](https://github.com/BuilderIO/qwik/tree/main/packages/qwik-city/middleware/netlify-edge) middleware
 
 In the future, we may add other middleware glue-code. However, even if the glue code is not provided it should be relatively easy to write your own glue code based on the `requestHandler()` function.
