+## Features
+
+- **File Display & Management**: Browse and edit code files
+- **Chat Interface**: AI-powered code assistant
+- **Code Execution**: Run Python code with debugging
+- **Internet Search**: Fetch documentation and examples
+- **System Prompts**: Context-aware AI interactions
+
+## Setup
+
+### 1. Activate Virtual Environment
+
+```bash
+# Windows
+.\.venv\Scripts\Activate.ps1
+
+# macOS/Linux
+source .venv/bin/activate
+```
+
+### 2. Install Dependencies
+
+```bash
+pip install -r requirements.txt
+```
+
+### 3. Run Application
+
+```bash
+streamlit run frontend/app.py
+```
+
+### 4. Run Tests
+
+```bash
+pytest tests/
+```
+
+## Architecture
+
+The application follows a frontend-backend split:
+
+- **Frontend**: Streamlit UI components (sidebar, editor, chat)
+- **Backend**: Specialized manager modules
+  - FileManager: File operations
+  - ChatManager: AI interaction
+  - SystemPrompter: Prompt management
+  - SearchManager: Internet search
+  - ExecutionEngine: Code execution
+  - DebugLogger: Error handling & logging
+
+## Development
+
+Use Git to track changes:
+
+```bash
+git add .
+git commit -m "Your message"
+git push origin sturcture
+```
