Introduction to Version Control

What is Version Control?

Version Control is a system that records changes to files or sets of files over time so that you can recall specific versions later. It is essential for tracking changes, collaborating with others, and maintaining a history of a project.

Importance of Version Control

Version control systems provide numerous benefits, including:

• Collaboration: Multiple people can work on the same project without conflicts.
• Backup: Previous versions can be restored easily.
• History: Detailed logs of changes can be reviewed.
• Branching: Experiment with new features without affecting the main project.

How Version Control Works

Version control works by keeping a complete history of changes made to files in a repository. Here’s a simple flow of how a typical version control operation works:

1. Create a repository.
2. Make changes to files.
3. Stage the changes.
4. Commit the changes with a message.
5. Push changes to a remote repository.

            C --> D[Stage Changes];
            D --> E[Commit Changes];
            E --> F[Push to Remote];
            F --> G[End];
