+
+## Features
+
+1. Agent logs into WhatsApp Web automatically
+2. Parses natural language scheduling instructions
+3. Composes personalized messages using AI
+4. Schedules messages for future delivery or sends immediately
+5. Persistent session (no repeated QR scanning)
+
+## Setup
+
+Make sure the newest version of browser-use is installed:
+```bash
+pip install -U browser-use
+```
+
+Export your Gemini API key, get it from: [Google AI Studio](https://makersuite.google.com/app/apikey)
+```bash
+export GOOGLE_API_KEY='your-gemini-api-key-here'
+```
+
+Clone the repo and cd into the app folder
+```bash
+git clone https://github.com/browser-use/browser-use.git
+cd browser-use/examples/apps/msg-use
+```
+
+## Initial Login
+
+First-time setup requires QR code scanning:
+```bash
+python login.py
+```
+- Scan QR code when browser opens
+- Session will be saved for future use
+
+## Normal Usage
+
+1. **Edit your schedule** in `messages.txt`:
+```
+- Send "Hi" to Magnus on the 13.06 at 18:15
+- Tell hinge date (Camila) at 20:00 that I miss her
+- Send happy birthday message to sister on the 15.06
+- Remind mom to pick up the car next tuesday
+```
+
+2. **Test mode** - See what will be sent:
+```bash
+python scheduler.py --test
+```
+
+3. **Run scheduler**:
+```bash
+python scheduler.py
+
+# Debug Mode - See the browser in action
+python scheduler.py --debug
+
+# Auto Mode - Respond to unread messages every ~30 minutes
+python scheduler.py --auto
+```
+
+## Programmatic Usage
+
+```python
+import asyncio
+from scheduler import schedule_messages
+
+async def main():
+    messages = [
+        "Send hello to John at 15:30",
+        "Remind Sarah about meeting tomorrow at 9am"
+    ]
+    await schedule_messages(messages, debug=False)
+
+asyncio.run(main())
+```
+
+## Example Output
+
+The scheduler processes natural language and outputs structured results:
+
+```json
+[
+  {
+    "contact": "Magnus",
+    "original_message": "Hi",
+    "composed_message": "Hi",
+    "scheduled_time": "2025-06-13 18:15"
+  },
+  {
+    "contact": "Camila", 
+    "original_message": "I miss her",
+    "composed_message": "I miss you ❤️",
+    "scheduled_time": "2025-06-14 20:00"
+  },
+  {
+    "contact": "sister",
+    "original_message": "happy birthday message", 
+    "composed_message": "Happy birthday! 🎉 Wishing you an amazing day, sis! Hope you have the best birthday ever! ❤️🎂🎈",
+    "scheduled_time": "2025-06-15 09:00"
+  }
+]
+```
