Version control systems track changes to code and enable collaboration among developers. Git has become the industry standard, and understanding it is essential for modern software development.
Repositories contain your project files and their complete history. Each commit creates a snapshot of your project at that moment, allowing you to review changes and revert if needed.
Branching allows parallel development without affecting the main codebase. Developers create branches for new features, work on them independently, then merge changes back when ready. This workflow enables teams to collaborate efficiently.
