What is Version Control?

Version control is a system that records changes to a file or set of files over time so you can recall specific versions later. It allows developers to track changes, collaborate with others, and manage projects more effectively.

Why Use Git?

Git is a distributed version control system that offers several advantages:

• Every developer has a full copy of the repository.
• Efficient branching and merging capabilities.
• Lightweight and fast operations.

Key Concepts

Git operates as a series of snapshots. Each time you commit, Git takes a picture of your project at that point in time. Here are some key terms:

• Repository: A directory where Git tracks changes.
• Commit: A saved snapshot of your project.
• Branch: A parallel line of development.

Installing and Configuring Git

To get started with Git, follow these steps:

1. Download Git from git-scm.com.
2. Install Git on your machine.
3. Configure Git with your name and email:

  git config --global user.name "Your Name"
  git config --global user.email "your.email@example.com"
          

Exercise: Setting Up Git

Practice setting up Git by completing the following steps:

• Install Git on your machine.
• Configure your username and email using the commands above.
• Run git config --list to verify your settings.
