Key concepts

Repository

In Git, a repository (or repo for short) is a data structure that stores all the revision history of a project.

Think of a repository as a digital archive that keeps track of every change made to the files in your project over time. This includes not only the current state of the files but also all previous versions, branches, tags, and metadata about those changes.

Since Git is a distributed version control system, each developer has their own local copy of the entire repository on their machine. These local repositories can be synchronized with a central remote repository hosted on servers or platforms like GitHub, GitLab, or Bitbucket. This setup allows multiple developers to collaborate on the same project, while being able to work independently and offline.

Examples

Initialize a new Git repository in the current directory:

git init

Clone a remote repository from the given URL to your local machine:

git clone https://github.com/user/project.git

Gitopedia is a companion to the main GitByBit course, designed to serve as your personal Git knowledge base. New topics unlock gradually as you progress, giving you time to build a solid mental model of Git.

Learning directly in VS Code lets you practice Git exactly as you would in real life, doing real work and writing real code. In addition, the course connects to your actual terminal, so it can point out mistakes and suggest workarounds when you need them.

The course is FREE, with no ads or other nonsense. An optional premium add-on focused on teamwork is available if you'd like to support my work (regrettably, I have to eat every day), but that's entirely up to you.
