+# SuperTokens EmailPassword with Cloudflare Workers (HonoJS) on Edge Runtime
+
+This demo app uses HonoJS with Cloudflare Workers for the backend server. We use [Wrangler](https://developers.cloudflare.com/workers/wrangler/) in the backend server to simulate the Cloudflare Worker runtime. This is a pure Edge runtime implementation (works without `nodejs_compat` flag).
+
+## Project setup
+
+Clone the repo, enter the directory, and use `npm` to install the project dependencies:
+
+```bash
+git clone https://github.com/supertokens/supertokens-node
+cd supertokens-node/examples/cloudflare-workers/with-be-emailpassword
+npm install
+```
+
+## Run the demo app
+
+This compiles and serves the React app and starts the backend API server on port 3001.
+
+```bash
+npm run start
+```
+
+The app will start on `http://localhost:3000`
