GitHub GH-900 Guide: GitHub Foundations

GitHub GH-900 exam guide covering repos, issues, pull requests, Actions basics, and everyday platform use.

This GitHub Foundations guide helps GH-900 candidates focus on what the exam tests, where close answers usually split, and which review page to use next.

Use the study plan to group permissions, workflow, and security choices, the cheat sheet for workflow recall, the sample questions for explanation-heavy practice, the FAQ for scope checks, the resources page for GitHub exam references, and the glossary when feature names blur together.
