Turns Codebase into Easy Tutorial with AI

![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)

> *Ever stared at a new codebase written by others feeling completely lost? This tutorial shows you how to build an AI agent that analyzes GitHub repositories and creates beginner-friendly tutorials explaining exactly how the code works.*

This is a tutorial project of [Pocket Flow](https://github.com/The-Pocket/PocketFlow), a 100-line LLM framework. It crawls GitHub repositories and builds a knowledge base from the code. It analyzes entire codebases to identify core abstractions and how they interact, and transforms complex code into beginner-friendly tutorials with clear visualizations. - Check out the [YouTube Development Tutorial](https://youtu.be/AFY67zOpbSo) for more! - Check out the [Substack Post Tutorial](https://zacharyhuang.substack.com/p/ai-codebase-knowledge-builder-full) for more! **🔸 🎉 Reached Hacker News Front Page** (April 2025) with >900 up‑votes: [Discussion »](https://news.ycombinator.com/item?id=43739456) **🔸 🎊 Online Service Now Live!** (May 2025) Try our new online version at [https://code2tutorial.com/](https://code2tutorial.com/) – just paste a GitHub link, no installation needed! ## ⭐ Example Results for Popular GitHub Repositories!

Clone this repository ```bash git clone https://github.com/The-Pocket/PocketFlow-Tutorial-Codebase-Knowledge ``` 3. Install dependencies: ```bash pip install -r requirements.txt ``` 4. Set up LLM in [`utils/call_llm.py`](./utils/call_llm.py) by providing credentials. By default, you can use the [AI Studio key](https://aistudio.google.com/app/apikey) with this client for Gemini Pro 2.5: ```python client = genai.Client( api_key=os.getenv("GEMINI_API_KEY", "your-api_key"), ) ``` You can use your own models. We highly recommend the latest models with thinking capabilities (Claude 3.7 with thinking, O1). You can verify that it is correctly set up by running: ```bash python utils/call_llm.py ``` 5. Generate a complete codebase tutorial by running the main script: ```bash # Analyze a GitHub repository python main.py --repo https://github.com/username/repo --include "*.py" "*.js" --exclude "tests/*" --max-size 50000 # Or, analyze a local directory python main.py --dir /path/to/your/codebase --include "*.py" --exclude "*test*" # Or, generate a tutorial in Chinese python main.py --repo https://github.com/username/repo --language "Chinese" ``` - `--repo` or `--dir` - Specify either a GitHub repo URL or a local directory path (required, mutually exclusive) - `-n, --name` - Project name (optional, derived from URL/directory 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) - `--language` - Language for the generated tutorial (default: "english") - `--max-abstractions` - Maximum number of abstractions to identify (default: 10) - `--no-cache` - Disable LLM response caching (default: caching enabled) The application will crawl the repository, analyze the codebase structure, generate tutorial content in the specified language, and save the output in the specified directory (default: ./output).

🐳 Running with Docker

To run this project in a Docker container, you'll need to pass your API keys as environment variables. 1. Build the Docker image ```bash docker build -t pocketflow-app . ``` 2. Run the container You'll need to provide your `GEMINI_API_KEY` for the LLM to function. If you're analyzing private GitHub repositories or want to avoid rate limits, also provide your `GITHUB_TOKEN`. Mount a local directory to `/app/output` inside the container to access the generated tutorials on your host machine. **Example for analyzing a public GitHub repository:** ```bash docker run -it --rm \ -e GEMINI_API_KEY="YOUR_GEMINI_API_KEY_HERE" \ -v "$(pwd)/output_tutorials":/app/output \ pocketflow-app --repo https://github.com/username/repo ``` **Example for analyzing a local directory:** ```bash docker run -it --rm \ -e GEMINI_API_KEY="YOUR_GEMINI_API_KEY_HERE" \ -v "/path/to/your/local_codebase":/app/code_to_analyze \ -v "$(pwd)/output_tutorials":/app/output \ pocketflow-app --dir /app/code_to_analyze ```

## 💡 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 - Check out the Step-by-step YouTube development tutorial:
