+# Claude Code Notification Hook
+
+A bash script that sends notifications to [telert.reily.app](https://telert.reily.app) when Claude Code events occur.
+
+## Features
+
+- Receives JSON input from Claude Code hooks
+- Extracts message, title, and session_id from the input
+- Sends formatted notifications to telert.reily.app
+- Includes project name and path in notifications
+
+## Setup
+
+1. Clone this repository:
+   ```bash
+   git clone git@github.com:zhigang1992/claude-code-notification.git
+   cd claude-code-notification
+   ```
+
+2. Set up your webhook URL:
+   ```bash
+   export TELERT_WEBHOOK_URL="https://telert.reily.app/t/YOUR-WEBHOOK-ID"
+   ```
+
+3. Make the script executable:
+   ```bash
+   chmod +x claude-notification-hook.sh
+   ```
+
+4. Configure Claude Code to use this hook by adding it to your settings.
+
+## Usage
+
+The script reads JSON from stdin and expects the following format:
+
+```json
+{
+  "message": "Your notification message",
+  "title": "Notification title",
+  "session_id": "optional-session-id"
+}
+```
+
+### Example
+
+```bash
+echo '{"message": "Test notification", "title": "Test"}' | ./claude-notification-hook.sh
+```
+
+## Environment Variables
+
+- `TELERT_WEBHOOK_URL` (required): Your telert.reily.app webhook URL
+
+## Notes
+
+- The script uses basic JSON parsing with grep and cut. For production use, consider using `jq` for more robust JSON parsing.
+- Notifications include the current working directory and project name for context.
+- The script has a 10-second timeout for sending notifications.
