Git is a free, open-source version control software. It was created by Linus Torvalds in 2005. This tool is a version control system that was initially developed to work with several developers on the Linux kernel.
This basically means that Git is a content tracker. So Git can be used to store content — and it is mostly used to store code because of the other features it provides.
Real life projects generally have multiple developers working in parallel. So they need a version control system like Git to make sure that there are no code conflicts between them.
Also, the requirements in such projects change often. So a version control system allows developers to revert and go back to an older version of their code.
If we want to start using Git, we need to know where to host our repositories.
A repository (or “Repo” for short) is a project that contains multiple files. In our case a repository will contain code-based files.
There are two ways you can host your repositories. One is online (on the cloud) and the second is offline (self-installed on your server).
There are three popular Git hosting services: GitHub (owned by Microsoft), GitLab (owned by GitLab) and BitBucket. We’ll use GitHub as our hosting service.
We can set up and use Git for our projects through the command line, Terminal for macOS and Command Prompt or PowerShell for Windows users.
