Git

Git is a decentralized version control system that monitors file versions, mainly utilized for managing source code in collaborative software development. It facilitates coordination among multiple programmers while maintaining a comprehensive history of changes, designed for speed, data integrity, and support for distributed, non-linear workflows.

Commands in Git are executed via the command line to interact with a repository. Although there are numerous commands, a select few are frequently employed to manage project history and collaborate with others. These fundamental commands are the foundation of most Git workflows.

Compose clear and informative commit messages to clarify the 'why' behind a change, rather than just the 'what.' Use the imperative form in your commit subject lines, such as 'Add feature' instead of 'Added feature.' This practice helps maintain a clean and comprehensible history.

Ensure commits are small and atomic, with each representing a single logical modification. This approach streamlines code reviews, bug identification, and the process of reverting changes if necessary. Always develop new features or fixes in separate branches to keep the main branch stable.

Although Git and GitHub are often used in tandem, they fulfill different yet complementary functions within the software development lifecycle.
