+### Upload a Worker Version
+
+To create a new version of your Worker that is not deployed immediately, use the `wrangler versions upload --experimental-versions` command. Worker versions created in this way can then be deployed all at once at a later time or gradually deployed using the `wranger versions deploy --experimental-versions` command or via the Cloudflare dashboard under the Deployments tab. For now, the `--experimental-versions` flag and wrangler v3.40.0 or above is required to use this feature.
