What is Git and Why Should You Use It?
Git is a version control system that records changes to a file or a set of files over time, and allows you to recall specific versions of the code later. Git also enables you to create branches, which are isolated environments for developing new features or fixing bugs, and merge them with the main branch when they are ready. Git also facilitates distributed development, which means that each developer can have their own local repository with a full history of commits, and sync their changes with a remote repository.
Git is a version control system
A version control system is a tool that helps you manage your code and track its history. It allows you to:
Revert files or the entire project back to a previous state
Compare changes over time
Identify who modified a piece of code and when
Resolve conflicts when multiple developers work on the same files
Backup your code and protect it from accidental loss or damage

Troubleshooting common errors
If you encounter any problems with your Git installation, here are some common errors and possible solutions:
'git' is not recognized as an internal or external command, operable program or batch file. This error usually occurs on Windows when Git is not added to your PATH environment variable. You can fix this by either reinstalling Git and choosing the option to add it to your PATH, or by manually adding the path to the Git executable to your PATH variable.
bash: git: command not found This error usually occurs on Linux or Mac when Git is not installed or not in your PATH environment variable. You can fix this by either installing Git using your package manager or by manually adding the path to the Git executable to your PATH variable.
fatal: unable to access ' Could not resolve host: github.com This error usually occurs when you try to access a remote repository on GitHub, but your network connection is not working or your firewall is blocking the access. You can fix this by checking your internet connection, your proxy settings, and your firewall rules.
