 ### How to enable caching
 
-`@opennextjs/cloudflare` uses [Workers KV](https://developers.cloudflare.com/kv/) as the cache for your Next.js app. Workers KV is [fast](https://blog.cloudflare.com/faster-workers-kv) and uses Cloudflare's [Tiered Cache](https://developers.cloudflare.com/cache/how-to/tiered-cache/) to increase cache hit rates. When you write cached data to Workers KV, you write to storage that can be read by any Cloudflare location. This means your app can fetch data, cache it in KV, and then subsequent requests anywhere around the world can read from this cache.
+`@opennextjs/cloudflare` supports multiple caching mechanisms through a project's OpenNext configuration.

+#### 3. Configure the cache
+
+In your project's OpenNext config, enable the KV cache and set up a queue.
+
+The memory queue will send revalidation requests to a page when needed, and offers support for de-duplicating requests on a per-isolate basis. There might still be duplicate requests under high traffic or across regions.
+
+```ts
+// open-next.config.ts
