What is Git

Also known as: version control, git repository, GitHub

Git build-up

Git branch and mergemain branchfeature branchcommitmerge

Git records every change as a commit: work happens on a side branch and merges safely back into the main line.

Definition

A system that tracks changes to code files, allowing multiple developers to collaborate without overwriting each other's work. It enables distributed, non-linear workflows across the whole team.

A distributed version control system designed to track changes in source code during software development, supporting non-linear workflows and team collaboration.

Why it matters

Git is the foundation of modern team coding. It allows your developers to work on new features simultaneously, keep track of every change made, and roll back code to a previous version if a bug is introduced in production.

Improvement tips

  • Commit your code changes frequently with clear, descriptive messages explaining what was changed and why.
  • Use branching strategies like Git Flow to isolate new features until they are tested and ready.
  • Integrate Git with code review processes to ensure all changes are checked before merging.

Common mistakes

  • Accidentally committing sensitive passwords, API keys, or configuration files into public Git repositories.
  • Writing vague commit messages like 'fixed stuff' or 'updates', making history searches useless.
  • Working directly on the main code branch, which risks breaking the application for other developers.

Deployment

The process of moving new code or updates from a developer's computer to a live server where customers can use it. It covers the build, test, and file-transfer steps needed to go live.

Staging

A private replica of your live website used to test new changes and features safely before releasing them to the public. It duplicates production to catch issues before public release.

TechnologyIntermediate

Production

The live version of your website or application that real customers see, interact with, and use to conduct business. It serves real end users with live data in the application's intended role.

Frequently asked questions

Do I need to understand Git before I start my business?
You do not need to learn how to use Git yourself, but you should know that it is the standard tool developers use to manage code. Knowing this helps you understand how developers collaborate and track their progress. It ensures you can ask for the repository when hiring a team.
When does Git first become relevant for a new business?
It becomes relevant the moment a developer starts writing custom code for your startup's website or app. Having them use Git from day one ensures that all code changes are saved and backed up securely. It protects your intellectual property if you change developers later.
What does it cost to set up Git for my startup?
The Git software itself is completely free and open-source. Storing your code repositories on popular platforms like GitHub or GitLab is free for small teams, with paid plans available for advanced security controls. This keeps your early software development tool costs very low.
Should I own the Git account where my startup's code is stored?
Yes, you should always create and own the company's official GitHub or GitLab account yourself, and then invite developers to it. This ownership ensures you retain control of your proprietary code if a contractor leaves. Letting developers store your code on their personal accounts is a major business risk.
Why does Git matter for a business already running?
Git allows your developers to build new features without breaking your live website by keeping code changes isolated. If a bug is introduced in production, Git allows developers to instantly roll back to the last stable version. This history tracking keeps your digital systems stable and maintainable.
What goes wrong when a developer does not use Git version control?
Without Git, developers risk overwriting each other's changes, leading to lost work and duplicated effort. If the server crashes, you could lose the entire application codebase with no way to recover it. It also makes debugging extremely difficult because there is no record of who changed what.
How do I start using Git for my existing custom software?
You can hire a developer to initialize a Git repository in your existing application directory and upload it to a secure hosting service like GitHub. This process takes only a few hours and does not interrupt your live site. It establishes a secure base for all future updates.
How do I use Git to protect my business from contractor dependencies?
By requiring all developers to push their code daily to your company's Git repository, you ensure you always have the latest version of your software. If a developer becomes unavailable, another developer can quickly download the code history and continue the work. It eliminates key-person dependencies in your IT operations.
What does Git actually mean in plain words?
Git is a system that acts like a track-changes tool for software code, saving every version of a file as edits are made. It allows multiple programmers to work on the same website code simultaneously without cluttering or overwriting each other's work.
Is using Git risky or complicated for non-technical owners?
It is not risky, and you do not need to use it yourself because your developers will handle it. The main thing to remember is to keep your login credentials secure. Understanding that Git is a safety net that protects your code helps reduce fears about software development.
Do I need to hire a separate manager to monitor Git?
No, Git runs automatically as developers write and save their code, so you do not need to hire a separate manager. Your developers or project lead will handle code reviews and merges using the platform. For small teams, standard developer practices are sufficient.
What is the difference between Git and GitHub?
Git is the software tool that tracks code history on a computer. GitHub is an online service that hosts those code history files in the cloud, allowing developers to share their work and collaborate easily over the internet.
