Domain 7: Benefits of the GitHub Community (10%)
Open Source on GitHub
Open source software has publicly available source code that anyone can view, modify, and distribute — subject to the license terms.
Open Source Benefits
- Transparency — code is visible to everyone
- Community contributions — anyone can suggest fixes or improvements
- Rapid iteration — more eyes find bugs faster
- Ecosystem — builds libraries, tools, and integrations
How to Contribute to Open Source
The standard workflow:
Fork repo → clone locally → create branch → make changes
→ push to fork → open PR → maintainer reviews → mergedExam Tip
You fork a public repo you don't own because you can't push directly. Your fork is your own copy. PRs go from your fork back to the upstream original.
CONTRIBUTING.md
Repositories often include a CONTRIBUTING.md file that explains:
- How to report bugs
- How to submit PRs
- Code style standards
- Development setup
GitHub surfaces this file when users open Issues or PRs, guiding contributors.
CODE_OF_CONDUCT.md
Sets community behavior expectations. GitHub provides the Contributor Covenant template. Violations can result in removal from the project or organization.
Licensing
Choosing the right license is critical for open source projects.
| License | Type | Key rule |
|---|---|---|
| MIT | Permissive | Keep copyright notice only |
| Apache 2.0 | Permissive | Keep copyright + patent clause |
| GPL v3 | Copyleft | Derivatives must also be GPL |
| AGPL v3 | Strong copyleft | Even network use triggers copyleft |
| BSD 2/3-clause | Permissive | Similar to MIT |
| Creative Commons | For content | Not intended for software |
| Unlicense | Public domain | No restrictions at all |
No License = No Permission
A repository with no license is NOT open source. All rights are reserved by the author by default — others cannot legally use, copy, or modify the code without explicit permission.
InnerSource
InnerSource applies open source development practices inside an organization — sharing code and collaboration patterns across teams without making code public.
| Aspect | Open Source | InnerSource |
|---|---|---|
| Visibility | Public (internet) | Internal (organization) |
| Contributors | Anyone worldwide | Org members only |
| Repo visibility | Public | Internal (GitHub Enterprise) |
| Benefits | Same patterns and tooling | Cross-team collaboration within company |
GitHub Feature
Internal repositories on GitHub Enterprise Cloud are the foundation for InnerSource — visible to all org members but not the public.
GitHub Profile
Your GitHub profile is your developer identity on the platform.
Profile README
Create a special repository named exactly the same as your username (e.g., gobinathm/gobinathm) with a README.md — GitHub displays it on your profile page.
Contribution Graph
The green squares activity graph shows daily commit activity. Contributions count when:
- Commits are made to the default branch
- Issues and PRs are opened
- PR reviews are submitted
- The repo is not a fork (by default)
Exam Tip
Contributions to private repositories also count on the graph if "Private contributions" is enabled in profile settings.
Pinned Repositories
Up to 6 repositories (including gists) can be pinned to your profile for visibility.
GitHub Marketplace
GitHub Marketplace is where developers and organizations find apps and Actions to extend GitHub workflows.
| Category | Examples |
|---|---|
| GitHub Apps | CI/CD tools, code review bots, project management integrations |
| GitHub Actions | Reusable workflow steps and full workflow templates |
| OAuth Apps | Third-party apps that authenticate via GitHub |
Apps can be:
- Free or paid (billed through GitHub)
- Installed at the organization or user level
- Granted specific repository permissions
GitHub Education
GitHub Education provides free access to GitHub tools and learning resources for students and educators.
| Program | Who it's for | What they get |
|---|---|---|
| GitHub Student Developer Pack | Verified students | Free tools: Copilot, cloud credits, domains, courses |
| GitHub Campus Expert | Student community leaders | Training, speaking opportunities, GitHub swag |
| GitHub Classroom | Educators | Assignment distribution, automated grading |
GitHub Stars Program
GitHub Stars is a recognition program for outstanding community members — developers who educate, inspire, and grow the GitHub community.
- Selected by GitHub (application + nomination)
- Recognized on GitHub's Stars page
- Get early access to features and GitHub events
GitHub Sponsors
GitHub Sponsors lets users and companies financially support open source developers directly through GitHub:
- Individual or organization sponsors
- Monthly recurring or one-time payments
- GitHub waives transaction fees (GitHub does not take a cut)
- Sponsors get recognition on the developer's profile
