+# Hello world - Cloudflare workers + Typescript example
+
+Sample project configuration of a Restate service using the TypeScript SDK and
+Cloudflare Workers.
+
+Have a look at the [TypeScript Quickstart guide](https://docs.restate.dev/get_started/quickstart?sdk=ts) for more information about the SDK.
+
+You can run locally with `npm run dev` and register to Restate with
+`restate dep add http://localhost:9080 --use-http1.1`. `--use-http1.1` is needed
+with the local Workers dev server, as it does not expose HTTP2.
+
+You can deploy to cloudflare with `npm run deploy` and register to Restate with
+`restate dep add https://restate-cloudflare-worker.<your-subdomain>.workers.dev`.
