+
+## Getting Started
+
+1. **Fork the repository on GitHub**:
+
+   Go to the [django-sage-tools](https://github.com/your-username/django-sage-tools) repository and click on the "Fork" button in the top-right corner.
+
+2. **Clone your fork locally**:
+
+   ```bash
+   git clone https://github.com/your-username/django-sage-tools.git
+   cd django-sage-tools
+   ```
+
+3. **Install dependencies using Poetry**:
+
+   If you don't have Poetry installed, you can install it by following the instructions on the [Poetry website](https://python-poetry.org/docs/#installation).
+
+   ```bash
+   poetry install
+   ```
+
+4. **Create a new branch for your feature or bugfix**:
+
+   ```bash
+   git checkout -b feature/your-feature
+   ```
+
+## Running Tests
+
+We use `pytest` for testing. To run the tests, execute:
+
+```bash
+poetry run pytest
+```
+
+Ensure that all tests pass before submitting a pull request.
+
+## Code Style
+
+We use `black` and `isort` to format our code. Please ensure your code is formatted correctly before submitting a pull request:
+
+```bash
+poetry run black .
+poetry run isort .
+```
+
+Additionally, we use `flake8` and `pylint` for linting. You can run these tools to check for code style issues:
+
+```bash
+poetry run flake8
+poetry run pylint sage_tools
+```
+
+## Pre-commit Hooks
+
+We use `pre-commit` to ensure code quality and consistency. Pre-commit hooks will run automatically before each commit to check and format the code.
+
+### Setting Up Pre-commit Hooks
+
+1. **Install pre-commit**:
+
+   ```bash
+   poetry add --dev pre-commit
+   ```
+
+2. **Install the pre-commit hooks**:
+
+   ```bash
+   poetry run pre-commit install
+   ```
+
+3. **Run pre-commit hooks manually (optional but recommended before committing)**:
+
+   ```bash
+   poetry run pre-commit run --all-files
+   ```
+
+The pre-commit configuration is defined in the `.pre-commit-config.yaml` file. Make sure to review and understand the hooks configured.
+
+## Submitting a Pull Request
+
+1. **Commit your changes**:
+
+   Write clear and descriptive commit messages. Follow the guidelines in the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) specification if possible.
+
+   ```bash
+   git commit -am 'feat: add new email feature'
+   ```
+
+2. **Push to the branch**:
+
+   ```bash
+   git push origin feature/your-feature
+   ```
+
+3. **Open a pull request on GitHub**:
+
+   Go to the original repository on GitHub and open a pull request. Provide a clear and descriptive title and description for your pull request. Link to any relevant issues or discussions.
+
+4. **Wait for review**:
+
+   One of the project maintainers will review your pull request. Be responsive to feedback and be prepared to make changes if necessary.
+
