Different Areas to Contribute To

Once you’ve set up your environment and are familiar with the project, you can explore the different areas where you can make a meaningful impact. Ultralytics offers several ways to get involved, and you can choose how to contribute based on your skills and interests. 

Here’s a look at some of the options:

• Documentation: Contributing to the documentation is a great way to dive into the project while honing your writing skills. You can help by improving existing documentation, adding missing details, or creating new guides that make it easier for others to contribute.
• Bug fixes: If you have some coding experience, consider working on bug fixes. These can range from minor adjustments to more complex problems, giving you the chance to make a tangible impact on the project.
• Feature enhancements: For those who are ready to dive deeper, working on feature enhancements can be both challenging and rewarding. This might involve adding new features, improving existing ones, or working on the project roadmap.
• Pull request reviews: Reviewing pull requests is another valuable way to contribute, especially if you’re familiar with the project’s standards and best practices. By providing feedback and suggesting improvements, you help maintain the quality and integrity of the codebase.
• Community discussions: Engaging in community discussions is an excellent way to contribute if you enjoy collaboration and sharing ideas. Participate in ongoing conversations, propose new ideas, or help others by offering your insights and solutions.

Each of these areas offers a unique way to contribute, and you can choose the one that best aligns with your strengths and interests. Remember, every contribution, no matter how small, plays a key role in helping Ultralytics grow and evolve.

Contributing to Ultralytics Open-Source Documentation

When contributing to Ultralytics documentation, be sure to review the existing documentation and check for any issues or discussions that highlight areas needing improvement. Doing so helps ensure your contributions are focused where they’re most needed. 

When writing or editing, keep in mind that it’s key to follow the project’s guidelines to maintain consistency. Here are a few formatting tips:

• Always use Markdown formatting.
• Start each document with a clear introduction, and keep your language simple and accessible. 
• Use bullet points for lists, descriptive text for links, and images under 1 MB to let pages load quickly.
• In case you have questions about formatting, an easy way to double-check your formatting is to check how previous documentation has been formatted.

‍

Once you've made your draft, it’s important to preview it by building the documentation locally. You can catch any issues before submitting. To do this, start by cloning the repository and navigating to the project directory:

git clone https://github.com/ultralytics/ultralytics
cd ultralytics

Next, you can install the necessary dependencies:

pip install -e ".[dev]"

Finally, serve the documentation locally to review your changes:

mkdocs serve -f mkdocs.yml

You can view the locally built docs by navigating to `http://127.0.0.1:8000/` in your web browser. 

After reviewing for clarity, accuracy, and consistency, you can submit a pull request with a clear description of the doc you’ve created. Be sure to place the doc in the appropriate section based on where it belongs and fits best (guides, solutions, integrations, etc.). Please also take a look at the index.md file for the relevant sections and the overall mkdocs.yml file, and make any updates as needed. Attention to detail will help the review process go smoothly and ensure your contribution is well-integrated into the project.

Things To Keep in Mind While Contributing to Open-Source Code

When making code contributions to the Ultralytics project, it's important to follow best practices that help guarantee your code is clean, maintainable, and easy to integrate. Here are some key points to keep in mind:

• Avoid code duplication: Reuse existing code wherever possible and minimize unnecessary arguments.
• Make smaller, focused changes: Focus on smaller, targeted changes rather than large modifications.
• Simplify or remove code: Look for opportunities to simplify the code or remove unnecessary parts.
• Write effective docstrings: Clearly explain what your code does and link to relevant resources.
• Avoid unnecessary dependencies: Only add dependencies if they are absolutely necessary.

‍

It’s also essential to consider the long-term maintainability of the codebase. Before making any changes, ask yourself whether your modifications might break someone’s existing code using Ultralytics. If so, consider how to address this and make sure your changes are as compatible as possible.

Once you've developed a piece of code to contribute, you’ll need to test it. You can use frameworks like pytest to test your changes before submitting them. Consistent code formatting is another aspect of your contribution that is very important. Tools like the Ruff Formatter can help you maintain stylistic consistency and detect any logical bugs or inconsistencies in your code. 

Reviewing Pull Requests

Reviewing pull requests (PRs) is a great way to contribute! A PR is raised when someone requests to merge their changes into the main project. It helps keep the Ultralytics project running smoothly. When you’re reviewing a PR, make sure you understand why the changes were made. The author should clearly explain the purpose and benefits of the update, and you should see evidence of thorough testing in their PR. 

‍

Let’s walk through a few key things to focus on.

• Check for unit tests: Check that the PR includes tests for new features or changes to confirm the code works as expected and doesn’t introduce issues.
• Review documentation updates: Verify that documentation is updated to reflect changes or new features, including examples, API references, and other relevant details.
• Evaluate performance impact: Consider how the changes affect performance. If needed, request performance benchmarks or additional testing.
• Verify CI tests: Ensure all Continuous Integration (CI) tests are passing, including checks for code formatting and unit test results.
• Collaborate on fixes: If any tests fail, work with the author to resolve issues before approving the PR.

As a reviewer be sure to provide feedback that is specific and clear about any issues or concerns. Offer suggestions for improvement and ask questions that help the author think through potential problems. Encourage them to follow best practices in coding, testing, and documentation, and don’t hesitate to point them to resources that can help. Last but not least, always recognize the effort the author put into the PR. Positive feedback helps maintain a friendly and collaborative atmosphere in the open-source community.
