Key concepts

Repository

In Git, a repository (or "repo" for short) is a data structure that stores all the files, folders, and revision history of a project. It is the central location where Git tracks changes made to the project files over time.

A Git repository makes it possible for developers to:

  • Track changes: It keeps a record of the entire history of changes made to the project. This allows developers to see who made changes, what changes were made, and when those changes were made.
  • Collaborate: Multiple developers can work on different features or fixes simultaneously without stepping on each other's toes. Changes can be merged, creating a cohesive project development workflow.
  • Roll back to previous versions: If something goes wrong, you can easily revert to a previous state of the project that was known to work well.

Repositories are the heart of Git's functionality, providing powerful tools for software development and version control.

Examples

Initialize a new Git repository in the current directory:

git init

Clone an existing repository from a remote location:

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

Hi! I'm Alex, creator of GitByBit.

And this is Gitopedia—a reference that summarizes knowledge in my Git course.

Gitopedia is designed to be a personal knowledge base. When you progress through the main Git course in VS Code, you unlock all of these topics, one by one, bit by bit. This gives you time to digest the information and gradually build the mental model of Git. Here's an example of how it works:

Learning directly in VS Code lets you practice Git exactly as you would in real life, doing real jobs, writing real code. In addition, the course has access to your actual terminal, so it can point out mistakes, suggest workarounds, etc.

The course is FREE, there are no Ads or other bullshit. There are optional premium add-ons you can purchase, mainly to support my work (regrettably, I have to eat every day), but that's totally up to you.
