+### How to try out the `@opennextjs/cloudflare` package
+
+You can simply install the package from npm as specified in the [OpenNext documentation](https://opennext.js.org/cloudflare/get-started).
+
+> [!note]
+> There are also prerelease packages that we automatically publish on branch pushes (using [`pkg.pr.new`](https://github.com/stackblitz-labs/pkg.pr.new)):
+>
+> - `https://pkg.pr.new/@opennextjs/cloudflare@main`:
+>
+>   Updated with every push to the `main` branch, this prerelease contains the most up to date yet (reasonably) stable version of the package.
+>
+> - `https://pkg.pr.new/@opennextjs/cloudflare@experimental`
+>
+>   Updated with every push to the `experimental` branch (when present), this prerelease contains the latest experimental version of the package (containing features
+>   that we want to test/experiment on before committing to).
+>
+> Which you can simply install directly with your package manager of choice, for example: `npm i https://pkg.pr.new/@opennextjs/cloudflare@main`
