GitHub / Foundational / GH-900
GitHub Foundations
Understand Git, collaborate through pull requests and choose the right GitHub development and governance tools.
THE REVISION PATH
Your topics, in order.
Read. Recall. Explain the alternative.
Git, Commits and GitHub Flow
Commit locally, share remotely, review before merging.
Repository Files, Templates and Visibility
A repository needs instructions as well as code.
Issues, Pull Requests and Shared Communication
Issues describe work; pull requests propose changes.
Actions, Copilot and Development Environments
Automation runs work; an editor changes files; a runtime executes them.
Projects, Milestones and Work Visibility
Track outcomes and flow, not just a pile of tickets.
Account Security, Teams and Repository Governance
Authenticate the person; authorize the action; protect the shared branch.
Open Source, InnerSource and Community
Visibility invites participation; a license defines reuse.
How this guide is organised
Original revision notes arranged around practical decisions. The current official study guide defines the mapped scope; GitHub technical documentation supports the explanations. Read, recall without looking, then explain why another option would fail.
