+## How to Use This Release
+
+1. **Start Interactive Mode**: `python main.py`
+2. **Describe Your Task**: The AI will break it down into steps
+3. **Watch Progress**: See detailed tool execution summaries
+4. **Get Results**: Files created, commands executed, problems solved
+
+### Example Session
+```
+python main.py
+> create a timer program that works on the cli
+🤖 AI will create files, test them, and ensure they work properly
+📁 Creating timer.py...
+✅ File created successfully at /path/to/timer.py
+🔧 Testing the program...
+✅ Timer program working correctly!
+```
+
+The AI now provides complete development assistance from conception to working code.
