What Is Git? Version Control Explained for Non-Technical Founders

Imagine building a complex document — a legal contract, a detailed business plan — without any ability to track changes, see what was different between versions, or undo a decision you made two weeks ago. You would be working blind, and any significant mistake could mean starting over or spending hours reconstructing what you had. That is what software development looks like without version control.

Git is the version control system used by virtually every professional software development team on the planet. It is not a nice-to-have. It is foundational infrastructure — as basic to software development as a ledger is to accounting. If your development team is not using Git, or is using it poorly, that is a serious operational risk to your project.

What Version Control Does

Version control is a system that tracks changes to a set of files over time. Every change is recorded, along with who made it, when they made it, and a description of what changed and why. You can view the full history of every file in the project, compare any two versions of any file, and restore any previous version at any point.

This capability has several practical consequences. When a bug is introduced, you can identify exactly which change caused it and when. When a feature needs to be reverted because it turns out to be wrong for the product, you can remove it without losing other work done in the same period. When a developer leaves the project and another takes over, the incoming developer can read the history of decisions made in the codebase.

Version control also enables multiple developers to work on the same codebase simultaneously without overwriting each other's work. Changes are made in isolated branches and merged together with conflict detection — a system that identifies when two changes to the same file are incompatible and requires a developer to resolve the conflict explicitly.

What Git Specifically Is

Git is the dominant version control system, created by Linus Torvalds — the same person who created the Linux operating system — in 2005. It is distributed, meaning every developer has a complete copy of the repository on their machine. This makes it fast (most operations do not require a network connection) and resilient (the repository is not dependent on a single server).

Git is used through a platform — most commonly GitHub, GitLab, or Bitbucket — that provides a web interface for viewing the repository, reviewing changes, managing access permissions, and integrating with other tools. GitHub is the most widely used and is where most open-source software lives. For your business project, you should have access to the repository where your software is stored.

Branches and What They Mean

One of Git's core concepts is branching. A branch is an independent copy of the codebase where work can happen without affecting the main version. Developers create branches for new features, bug fixes, and experiments. When the work is complete and reviewed, it is merged back into the main branch.

This workflow means the main branch — the version of the software that gets deployed to production — is always in a stable, deployable state. No in-progress work lands in production until it is finished, reviewed, and tested. Branches keep development organized and make it clear what work is done versus what is still in progress.

When your development team deploys a new version of your software, they should be deploying from a specific, tagged version of the main branch — not from whatever happens to be in someone's local copy. This traceability is not bureaucratic overhead. It is how you know exactly what is running in production.

Commit Messages and Project History

Every change recorded in Git is called a commit. Each commit has a message — a description written by the developer explaining what the change does and why. Good commit messages create a readable narrative of how the software evolved: not just what changed, but the reasoning behind each decision.

This history is more valuable than most people expect. When you come back to a piece of code six months later and cannot remember why it was written a certain way, the commit history often holds the answer. When a bug surfaces that you thought was fixed, the commit history shows whether the fix was actually applied and when.

Ask your development team how they write commit messages. Ask whether they have a standard. Teams with good Git discipline write clear, purposeful commit messages. Teams without that discipline write messages like "fix bug" or "update stuff" — which is worse than no message at all because it creates the illusion of documentation without the substance.

What You Should Require as a Business Owner

First, require access to the repository. You should be able to view the codebase, the commit history, and the open and closed branches at any time. If your development team stores the code in a private repository you cannot access, you have no visibility into what is being built or the state of the work.

Second, require that the main branch is protected — meaning changes can only be merged after code review. This is a Git configuration, and it takes about thirty seconds to set up. If it is not in place, developers can push untested code directly to production.

Third, require that branches are used for all development work and that the main branch reflects what is running in production. The commit history should show a clear record of what changed and when.

Fourth, ensure that the repository is not the only copy of your code. Repository hosting platforms like GitHub provide backups, but you should also understand what happens to your code if the relationship with your development firm ends. The repository should be in an account you own, or there should be a clear contractual agreement about code ownership and access.

At Routiine LLC, all projects are managed through Git with protected main branches, required code review, and repositories owned by the client.
