Using Git in a Team Project
Introduction
Git is a version control system that allows you to track changes to your code over time. It is a powerful tool that allows you to collaborate with others on a project, and is a standard tool in the software development industry.
This is not a comprehensive guide to Git, but rather a quick introduction to the most common commands you will use when working on a team project.
Feel free to use this as a reference, but you will likely need to do additional research to learn more about Git.
