As discussed earlier, Git is a distributed version control system (DVCS) that allows multiple developers to work on a project simultaneously. Instead of relying on a central server, every developer has a complete copy of the project, ensuring data integrity, collaboration, and efficient tracking of changes.

This diagram shows how multiple developers collaborate using Git. Each developer has their own local version of the project, called a Working Copy, where they make changes. These changes are then pushed to a shared Repository. Other team members can pull those changes into their own working copies. This setup allows the whole team to work on the same codebase at the same time without conflicts.

What is GitHub?

GitHub also includes collaboration features such as pull requests, issues, and code reviews, enabling teams to work together efficiently. Additionally, it supports Continuous Integration (CI) and project management tools, streamlining workflows and automating testing and deployment processes. These features make GitHub a powerful platform for modern software development and DevOps practices.

Now let's refresh our knowledge of the four essential Git commands (see more at the Git Course here).

These four Git commands — init, add, commit, and push — form the core of version control. They help you start tracking your project, save changes, and share your work with others.
