+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+
+## Notification Setup (Discord/Telegram)
+
+To receive alerts when someone cancels a cat sitting slot, you can configure a Webhook in the **Settings** menu of your dashboard.
+
+### 👾 Discord
+1. Open your Discord server and go to **Server Settings** > **Integrations** > **Webhooks**.
+2. Click **New Webhook**, name it (e.g., "Cat Sitting Bot"), and select the desired channel.
+3. Click **Copy Webhook URL**.
+4. Paste this URL into the **Notification Webhook** field in the plan settings.
+
+### ✈️ Telegram
+Telegram doesn't support simple Webhooks natively for users. The easiest way is using a bridge like **Intergram**:
+1. Open Telegram and search for the `@IntergramBot`.
+2. Send `/start` to get your unique **Chat ID**.
+3. Your Webhook URL will be: `https://www.intergram.xyz/msg/YOUR_CHAT_ID`
+4. Paste this URL into the **Notification Webhook** field in the plan settings.
+
+*Note: The app sends notifications automatically whenever a booking is deleted.*
+
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.

+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
