+# Contributing to Optimas
+
+Thank you for your interest in contributing to Optimas! We welcome contributions from the community.
+
+## How to Contribute
+- **Bug Reports & Feature Requests:** Please use [GitHub Issues](https://github.com/snap-stanford/optimas/issues ).
+- **Pull Requests:** Fork the repo, create a feature branch, and submit a pull request (PR) with a clear description.
+- **Discussions:** For design or usage questions, open a GitHub Discussion or join our community chat.
+
+## Code Style & Quality
+- Follow [PEP 8](https://peps.python.org/pep-0008/) and [PEP 621](https://peps.python.org/pep-0621/) standards.
+- All code must pass [ruff](https://docs.astral.sh/ruff/), [black](https://black.readthedocs.io/en/stable/), and [isort](https://pycqa.github.io/isort/) checks.
+- Use type hints where possible.
+
+## Development Setup
+
+### Using [uv](https://github.com/astral-sh/uv) (recommended)
+[uv](https://github.com/astral-sh/uv) is a fast, modern Python package and dependency manager. You can use it for all dependency management and lockfile generation in Optimas.
+
+1. Install uv:
+   ```bash
+   pip install uv
+   ```
+2. Install all dependencies (including dev tools):
+   ```bash
+   uv pip install .[dev]
+   ```
+3. (Optional) Generate a lock file for reproducibility:
+   ```bash
+   uv pip compile pyproject.toml > uv.lock
+   ```
+4. Run tests:
+   ```bash
+   pytest
+   ```
+
+### Traditional pip (alternative)
+1. Install dependencies:
+   ```bash
+   pip install -r requirements.txt
+   # or, for full dev setup:
+   pip install .[dev]
+   ```
+2. Run tests:
+   ```bash
+   pytest
+   ```
+
+## Pre-commit Hooks
+- We use [pre-commit](https://pre-commit.com/) to enforce code style and quality.
+- Hooks: ruff, black, isort, end-of-file-fixer.
+- Run `pre-commit run --all-files` before pushing.
+
+## Submitting a Pull Request
+- Ensure your branch is up to date with `main`.
+- All tests and pre-commit hooks must pass.
+- Add/Update documentation and tests as needed.
+- Add a changelog entry in `CHANGELOG.md` if your PR is user-facing.

 Remember to include WANDB_ENTITY and WANDB_PROJECT in the `.env` file or export them in your shell.
 
+## 🚀 GEPA Integration
+
+Optimas includes GEPA (Generate, Evaluate, Predict, and Adapt) for automatic prompt optimization.
+
+```bash
+# Quick demo with local models
+ollama pull llama3.1:8b && ollama pull qwen3:8b
+
+# Basic GEPA demo (BaseComponent)
+python examples/gepa/demo_gepa.py
+
+# DSPy vs BaseComponent comparison
+python examples/gepa/demo_gepa_dspy.py
+```
+
+**GEPA works with both DSPy signatures and BaseComponent classes**, automatically detecting the framework and using the appropriate optimization path.
+
+📖 **See [examples/gepa/GEPA_GUIDE.md](examples/gepa/GEPA_GUIDE.md) for complete setup and usage instructions.**
