+## 🚀 Getting Started
+
+1. Clone this repository
+
+2. Install dependencies: 
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+3. Generate a complete codebase tutorial by running the main script:
+
+  ```bash
+  python main.py https://github.com/username/repo --include "*.py" "*.js" --exclude "tests/*" --max-size 50000
+  ```
+  
+  - `repo_url` - URL of the GitHub repository (required)
+  - `-n, --name` - Project name (optional, derived from URL if omitted)
+  - `-t, --token` - GitHub token (or set GITHUB_TOKEN environment variable)
+  - `-o, --output` - Output directory (default: ./output)
+  - `-i, --include` - Files to include (e.g., "*.py" "*.js")
+  - `-e, --exclude` - Files to exclude (e.g., "tests/*" "docs/*")
+  - `-s, --max-size` - Maximum file size in bytes (default: 100KB)
+
+- Crawl GitHub repositories at specific commits or branches
+- Filter files by patterns (include/exclude)
+- Set maximum file size limits
+- Generate relative paths for simpler directory structures
+
+The application will crawl the repository, analyze the codebase structure, generate tutorial content, and save the output in the specified directory (default: ./output).
+
+
+## 💡 Development Tutorial
+
+- I built using [**Agentic Coding**](https://zacharyhuang.substack.com/p/agentic-coding-the-most-fun-way-to), the fastest development paradigm, where humans simply [design](docs/design.md) and agents [code](flow.py).
+
+- The secret weapon is [Pocket Flow](https://github.com/The-Pocket/PocketFlow), a 100-line LLM framework that lets Agents (e.g., Cursor AI) build for you
