+# Contributing to Airflow API Client
+
+Thank you for your interest in contributing. This document covers how to set up a development
+environment, the coding standards we follow, and the process for submitting changes.
+
+> **Note:** This file has been reviewed and approved by Rackspace Legal. Do not modify the
+> DCO section or the contribution process without seeking Legal review again.
+
+## Developer Certificate of Origin (DCO)
+
+This project uses the [Developer Certificate of Origin (DCO)](https://developercertificate.org/)
+rather than a Contributor Licence Agreement (CLA). By submitting a pull request you certify that
+you have the right to contribute the code and that you agree to the DCO terms.
+
+Every commit must include a `Signed-off-by` trailer with your real name and email address:
+
+```
+Signed-off-by: Jane Smith <jane.smith@example.com>
+```
+
+Add it automatically with:
+
+```bash
+git commit -s -m "your commit message"
+```
+
+If you forget on a previous commit:
+
+```bash
+git commit --amend -s --no-edit
+```
+
+Pull requests with unsigned commits will not be merged.
+
+## Development setup
+
+Requires Python 3.10+ and [uv](https://github.com/astral-sh/uv).
+
+```bash
+git clone https://github.com/rackerlabs/airflow-api-client.git
+cd airflow-api-client
+uv sync --extra dev
+```
+
+Install pre-commit hooks (runs Black, isort, and Pylint before each commit):
+
+```bash
+uv run pre-commit install
+```
+
+## Code style
+
+| Tool | Purpose |
+|---|---|
+| [Black](https://black.readthedocs.io/) | Formatting (line length 100) |
+| [isort](https://pycqa.github.io/isort/) | Import ordering |
+| [Pylint](https://pylint.readthedocs.io/) | Linting |
+| [Flake8](https://flake8.pycqa.org/) | Additional style checks |
+
+Run all checks manually:
+
+```bash
+uv run black airflow_api_client/ tests/
+uv run isort airflow_api_client/ tests/
+uv run pylint --rcfile=pyproject.toml airflow_api_client/
+uv run flake8 airflow_api_client/ tests/
+```
+
+The pre-commit hooks run Black, isort, and Pylint automatically on `git commit`.
+
+## Running tests
+
+```bash
+uv run pytest tests/
+```
+
+## Submitting a pull request
+
+1. Fork the repository and create a branch from `main`.
+2. Make your changes with signed-off commits (see DCO above).
+3. Ensure all tests pass and linters report no errors.
+4. Open a pull request against `main`. CI must pass before the PR can be merged.
+5. A maintainer will review your PR and may request changes.
+
+Please keep pull requests focused — one logical change per PR makes review faster.
+
+The current maintainers are listed in [MAINTAINERS](MAINTAINERS).
+
+## Reporting bugs
+
+Open a GitHub issue with steps to reproduce, the command you ran, and the full error output.
