What is Git? — UK Software Development Guide
Direct Answer
Git is a distributed version control system that tracks changes to source code over time. Every developer has a complete copy of the repository's history. Git's branching model allows parallel development on multiple features simultaneously. The most popular Git hosting platforms are GitHub, GitLab, and Bitbucket.
Git in the UK
Git is the universal version control system for UK software development — every ClickMasters project uses Git. UK regulatory relevance: Cyber Essentials expects documented development processes — Git commit history provides an audit trail of all code changes. UK GDPR: source code repositories must not contain personal data (hardcoded credentials, test data with real names) — ClickMasters includes git history scanning (git-secrets, Gitleaks) in CI/CD pipelines. NHS DSP Toolkit: change management evidence is partially provided by Git pull request history and code review records.
