+> This feature is experimental. We appreciate that you let us know of any issues that you find.
+
+To start using the Cloudflare Pages Next builder, start by replacing the builder executor in your application `project.json`.
+
+```json
+  ...
+  "targets": {
+    ...
+    "build": {
+      "executor": "@naxodev/nx-cloudflare:next-build",
+      ...
+    },
+    ...
+```
+
+Notice that you can use the same configurations as in the `@nx/next:build` executor.
+
+Now you can run the build command.
+
+```sh
+nx build <app-name>
+```
+
+And upload the content of the folder `.vercel/output/static` contained in the folder matching your configured output path.
