Welcome to the Git and GitHub course! In this module, we will learn the basic concepts of Git and GitHub, and how these tools can help you manage your code efficiently.

What is Git?

Git is a distributed version control system, created by Linus Torvalds in 2005. This system allows multiple developers to work on the source code simultaneously, maintaining a complete history of all changes made. Some of the key features of Git include:

• Fast and efficient: Git is designed to be fast in handling large projects and large sets of changes.
• Distributed: Every copy of a Git repository is a complete repository with a full history.
• Secure: Uses SHA-1 to ensure the integrity of the code and history.

What is GitHub?

GitHub is a platform for hosting your Git repositories in the cloud. Beyond simple storage, GitHub offers a number of additional features that facilitate project collaboration and management, such as:

• Public and private repositories: You can host both open and private projects.
• Pull requests: Facilitate code review before merging into the main branch.
• Issues: Tool for tracking tasks, bugs, and improvements.
• Actions: For continuous integration and deployment.

How do they work together?

While Git handles version control on your local machine, GitHub acts as a remote repository where your team can collaborate and manage the code. The common interaction between Git and GitHub follows these steps:

1. Creating a local repository: Using Git on your local machine.
2. Cloning repositories: Downloading a copy of the remote repository to your local machine.
3. Commit changes: Saving specific points in the project's history to your local repository.
4. Push to the remote repository: Uploading your local commits to GitHub so others can see and collaborate on them.

Benefits of using Git and GitHub

• Detailed history: Every change is recorded in detail, allowing you to revert to any previous state of the project.
• Parallel work: Various developers can work on different features simultaneously.
• Improves collaboration: With code review and issue management tools, tasks can be assigned, reviewed, and discussed with ease.

In the next module, we will cover how to install and configure Git so you can start using these powerful tools.
