What is the relationship between the GIT version control system and the GitHub repository hosting platform?

Git is a distributed version control system that allows developers to track changes in code, work with branches, and merge changes. GitHub, on the other hand, is a cloud platform for hosting Git repositories, providing a user-friendly web interface, collaboration tools (pull requests, code review), integrations, and automation.

The relationship between them is that GitHub uses Git as the foundation for version control, and also extends Git's capabilities by providing services for collaborative development, code storage, and project management. Developers work locally with Git, then push changes to a repository on GitHub, where the code is accessible to the team and other participants.

Example usage:

# Cloning a repository from GitHub
git clone https://github.com/user/repo.git

# Creating a new branch
git checkout -b feature-branch

# Adding changes and committing
git add .
git commit -m "Added a new feature"

# Pushing changes to GitHub
git push origin feature-branch

Thus, Git is a version control tool, and GitHub is a platform that facilitates collaborative work with Git repositories.
