Open Source Contribution Workflow

Introduction

Contributing to open source can seem intimidating at first, but following a clear workflow makes the process smooth and productive. This guide covers the standard, step-by-step process from finding a repository to submitting your changes, ensuring your contribution is easy for maintainers to review and merge.

1. Fork the Repository

The first step is to create a personal copy of the project, called a fork. This allows you to work on the codebase without affecting the original project (also known as the "upstream" repository).

• Click the "Fork" button on the original repository's GitHub page.
• This creates a copy of the project under your personal GitHub account.
• Next, clone your fork to your local machine to start working.

# Clone your fork locally to your machine
git clone https://github.com/your-username/repo-name.git

# Navigate into the project directory
cd repo-name

Tip: Add the original repository as an "upstream" remote to easily sync your fork with the latest changes.

git remote add upstream https://github.com/original-owner/repo-name.git

2. Create a Branch

It's a best practice to never work directly on the main or master branch. Instead, create a new, separate branch for each feature or fix you plan to work on.

• Name your branches descriptively to indicate the purpose of your changes.
  • Features: feature/add-user-profile
  • Bug Fixes: fix/navbar-overlap
  • Documentation: docs/update-readme
• Use a short, focused branch name to make pull requests easier to review.

# Create and switch to a new branch for your changes
git checkout -b feature/add-login

3. Make Your Changes

Once you're on your new branch, you can begin making your contributions.

• Commit changes frequently: Make small, atomic commits that focus on a single, logical change. This makes your work easy to follow.
• Follow project conventions: Adhere to the project’s code style, linter rules, and commit message conventions (often found in the CONTRIBUTING.md file).
• Keep your changes atomic: Each commit should be a self-contained unit of work. For example, don't mix a bug fix and a new feature in the same commit.

4. Sync with Upstream

Before submitting your pull request, it's crucial to ensure your branch is up-to-date with the original repository. This helps you resolve any conflicts locally and keeps the project's history clean.

# Fetch the latest changes from the original repository
git fetch upstream

# Rebase your branch on top of the latest upstream/main
git rebase upstream/main

Rebasing rewrites your commit history to appear as if you started with the latest code, which is cleaner than a merge.

5. Open a Pull Request (PR)

A Pull Request is your proposal to merge your changes into the original project.

• Push your branch to your fork:

  git push origin feature/add-login

• Open the Pull Request: On your GitHub fork's page, a button will appear to open a new PR.
• Fill out the PR template: A good PR description is key to a smooth review process. Be sure to include:
  • What changed: A clear summary of your code changes.
  • Why it changed: The motivation behind the change (e.g., "to fix a bug" or "to add a new feature").
  • Related issues: Link to any relevant issues or discussions (e.g., Closes #123).
  • How you tested it: Explain the steps you took to verify your changes work as expected.

6. Respond to Review Feedback

After you open a PR, a maintainer will review your code. This is a collaborative process.

• Be respectful and open to suggestions: Review feedback is an opportunity to learn and improve.
• Make required changes in your branch: Once you make the changes, just push them to your branch, and they will automatically update in the PR.
• Acknowledge and thank the reviewer: A simple "Thanks for the feedback!" can go a long way.

7. Merge and Clean Up

Once your PR is approved, a maintainer will merge your changes.

• Delete merged branches: After the merge, it’s good practice to delete your local and remote branches to keep your workspace and the repository organized.

  # Delete the local branch
  git branch -d feature/add-login
  
  # Delete the remote branch on your fork
  git push origin --delete feature/add-login

8. Best Practices for Contributors

• Start with good first issue: If you're new to a project, these labeled issues are perfect for getting familiar with the codebase.
• Read the CONTRIBUTING.md file: This document is the ultimate guide to the project’s specific rules and expectations.
• Test your changes thoroughly: Don't rely on the project's automated tests alone. Test your changes locally to ensure they work as expected.
• Communicate clearly: Be active in the PR comments and on issues. Clear communication prevents misunderstandings.
• Avoid submitting large, unfocused PRs: Small, targeted PRs are much easier and faster to review.

Summary

Following a structured workflow ensures your contributions are clean, reviewable, and easy to merge. It shows respect for the maintainers' time and helps you become a valuable member of the open-source community.
