# Development Contributions

We strive to make contributions **easy, collaborative, and enjoyable**. Follow the steps below to ensure a smooth contribution process.

## Submitting Your Contribution through PR

To contribute, follow these steps:

1. **Fork & Clone** the repository: [Mem0 on GitHub](https://github.com/mem0ai/mem0)
2. **Create a Feature Branch**: Use a dedicated branch for your changes, e.g., `feature/my-new-feature`
3. **Implement Changes**: If adding a feature or fixing a bug, ensure to:
   - Write necessary **tests**
   - Add **documentation, docstrings, and runnable examples**
4. **Code Quality Checks**:
   - Run **linting** to catch style issues
   - Ensure **all tests pass**
5. **Submit a Pull Request**

For detailed guidance on pull requests, refer to [GitHub's documentation](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request).

## Dependency Management

We use `hatch` as our package manager. Install it by following the [official instructions](https://hatch.pypa.io/latest/install/).

**Do NOT use `pip` or `conda` for dependency management.** Instead, follow these steps in order:

```bash
# 1. Install base dependencies
make install

# 2. Activate virtual environment (this will install dependencies)
hatch shell  # For default environment
hatch -e dev_py_3_11 shell  # For dev_py_3_11 (differences are mentioned in pyproject.toml)

# 3. Install all optional dependencies
make install_all
```

## Development Standards

### Pre-commit Hooks

Ensure `pre-commit` is installed before contributing:

```bash
pre-commit install
```

### Linting with `ruff`

Run the linter and fix any reported issues before submitting your PR:

```bash
make lint
```

### Code Formatting

To maintain a consistent code style, format your code:

```bash
make format
```

### Testing with `pytest`

Run tests to verify functionality before submitting your PR:

```bash
make test
```

**Note:** Some dependencies have been removed from the main dependencies to reduce package size. Run `make install_all` to install necessary dependencies before running tests.

## Release Process

Currently, releases are handled manually. We aim for frequent releases, typically when new features or bug fixes are introduced.
