Three Essential Git Practices Every Developer Should Follow

Three Git Recommendations

Version control systems are essential tools for any software project, providing benefits such as change tracking, easy rollback, and collaborative visibility.

Without a VCS, files can be overwritten or lost, and it is difficult to identify who made changes or why. With a VCS, developers commit changes, browse history, use branching and tagging for releases, and restore previous versions effortlessly.

Git and Mercurial are free, open‑source options, and services like GitHub or Bitbucket make remote hosting simple.

1. Put Everything Under Version Control

All project artifacts—source code, tests, documentation, configuration files, scripts, database schemas, and infrastructure‑as‑code definitions—should be versioned. This ensures new team members can quickly obtain the latest version and that environments (test, production) can be reproduced from a known state.

2. Commit Frequently with Appropriate Granularity

Frequent, small commits keep the history clear, reduce merge conflicts, and make it easy to revert or cherry‑pick specific changes. Each commit should represent a single, related change, such as a new feature or a bug fix, rather than mixing unrelated modifications.

3. Write Good Commit Messages

A commit message should include a concise summary describing why the change was made, not just what files were altered. It may also detail the motivation, the underlying solution, potential side effects, and any related issue‑tracker IDs.

Clear messages improve team collaboration, maintenance, and future debugging.
