 ## Usage
 
 Turbopack FileSystem Cache enables Turbopack to reduce work across `next dev` or `next build` commands. When enabled, Turbopack will save and restore data to the `.next` folder between builds, which can greatly speed up subsequent builds and dev sessions.
 
-> **Warning:** FileSystem Cache is still under development and is not yet stable. Users adopting should expect some stability issues.
-
-> **Good to know**: Note that while `next dev` and `next build` can share cached data with each other, most cache entries are command-specific due to different configuration and environment variables.
+> **Good to know:** The FileSystem Cache feature is Beta and is still under development. Users adopting should expect some stability issues. We recommend first adopting it for development.

 ### Build Caching
 
-Webpack supports [disk build caching](https://webpack.js.org/configuration/cache/#cache) to speed up builds. We are planning to support an analogous feature in Turbopack but it is not ready yet. On the `next@canary` release you can experiment with our solution by enabling the [`experimental.turbopackFileSystemCacheForDev`/`experimental.turbopackFileSystemCacheForBuild` flags](/docs/app/api-reference/config/next-config-js/turbopackFileSystemCache).
+Webpack supports [disk build caching](https://webpack.js.org/configuration/cache/#cache) to improve build performance. Turbopack provides a similar opt-in feature, currently in beta. Starting with Next 16, you can enable Turbopack’s filesystem cache by setting the following experimental flags:
