-Medusa Cache is enabled by default for all environments and plans if your Medusa project is running [Medusa v2.11.0 or later](https://github.com/medusajs/medusa/releases/tag/v2.11.0). No configuration is required to start using caching.
+To enable Medusa Cache for your Medusa project deployed on Cloud, set the `caching` feature flag in `medusa-config.ts`:
+
+```ts title="medusa-config.ts"
+module.exports = defineConfig({
+  // ...
+  featureFlags: {
+    caching: true
+  }
+})
+```
+
+This will enable all Medusa Cache functionality in your project.
