8. Explore the GitHub Community (5-10%)
The smallest domain by weight, but not by relevance — this phase covers what makes GitHub more than a private code host: open source licensing and funding, the tools that support open-source projects, ways to stay connected to other users' work, the Marketplace, and how open-source-style collaboration shows up even inside private companies through InnerSource.
Think of open source as GitHub's original reason for existing — without a shared, public place to collaborate on code, most of what makes the platform distinctive wouldn't exist, which is exactly the context the exam tests when it asks why a repository needs a license at all. ⚠️ Exam Trap: a public repository without a LICENSE file is not automatically open source for reuse — by default, all rights are reserved to the owner.
