 This is a template repository for quickly getting started with a Webhook App,
 which can be used for setting up Webhooks for listening to blockchain event notifications.
 
-## Local Webhook App
-
-To set up the template, run the following commands from this `webhook` folder:
-
-```bash
-npm install
-npm run start-webhook-app
-```
-
-This command will set up a webhook app locally.
-
-Once the local webhook app is setup, in another terminal window, you can test it with:
-
-```bash
-curl -X POST -H "Content-Type:application/json" -d '{"app": "webhook"}' http://localhost:3000/callback
-```

-
-```bash
-ssh -p 443 -R0:localhost:3000 -L4300:localhost:4300 qr@a.pinggy.io
-```
-
-You can also use [Vercel](https://vercel.com/) or other hosting solutions for your webhook app.
+You can use [webhook.site](https://webhook.site/) or [Vercel](https://vercel.com/) or other hosting solutions to create a simple webapp with public facing URL which can receive data from webhook POST calls.
