Understanding how GitHub works is often a challenge for beginners in the software development world. Terms like repository, commit, and pull request might sound complicated. However, the core concept is actually very close to the collaboration tools we use every day.

To make it easier to visualize, let’s compare GitHub to Google Docs, but specifically designed for writing program code.

What Is GitHub?

Simply put, GitHub is a cloud-based storage platform for program code. Just like how you use Google Docs to write documents with teammates without worrying about overwriting files, GitHub does the same for computer code.

Behind its simplicity, GitHub uses a version control system called Git.

Getting to Know “Git”: The Time Machine Behind GitHub

Before diving deeper into how GitHub works, we need to understand Git. Git acts like a time machine. Every time you complete an important part of your code, you save its state (called a commit).

If an error occurs, you can easily turn back time to the version before the error happened without having to create multiple file copies like thesis_final_v2.docx.

4 Main Steps of How GitHub Works

The workflow on GitHub generally follows these main steps:

  1. Creating a Repository (Repo): An online storage space containing all the files of a software project.
  2. Cloning & Committing (Clone & Commit): Downloading the project to your personal computer (clone), then saving changes locally (commit).
  3. Pushing Changes (Push): Uploading the work from your local computer back to GitHub.
  4. Merging Work (Pull Request): Submitting a request to merge your code into the main project after being reviewed by the team (merge).

Benefits of Using GitHub

  • Secure Backup: All projects are safely stored in the cloud.
  • Neat Collaboration: Team members can work simultaneously without breaking each other’s code.
  • Digital Portfolio: A GitHub account serves as an interactive CV to showcase the projects you have built.

Conclusion

Understanding how GitHub works helps you collaborate on software development safely, structurally, and efficiently.
