Git & GitHub, Step by Step from the Fundamentals - Fundamental Git [Complete Edition]

Step by step from the fundamentals

Git vs GitHub❓

💻 Git

Git is a program that manages versions of code. Just like creating SAVE points in a game, Git allows you to create SAVE points for your code and revert to any desired point in time. Not only that, but it also helps multiple colleagues work simultaneously on a single project by utilizing a powerful feature called 'branches'.

🌐 GitHub

First, we need to clarify that Git and GitHub are completely different concepts. Just as baseball and soccer are different, Git and GitHub are also different from each other. Git is a tool for version control, and GitHub is a space where you can store those versions. That's why GitHub is often compared to Google Drive or Dropbox.

Learn Git & GitHub properly, all at once.

Everyone can relate to the importance of Git. No matter what we build, we always end up using Git. Therefore, you need to properly understand Git. If you simply memorize commands like a machine, you'll end up wandering around blogs searching for answers. Learn properly from the basics to the principles all at once. I can assure you, after taking 'Fundamental Git', you'll be able to solve 99% of errors on your own.

Target Audience

❓ With so many Git courses out there, why was Geunbon Git created?

While working as a programming instructor, I realized something. Many students only memorize Git commands without properly understanding how it works. As a result, they couldn't use Git efficiently and often encountered situations where they couldn't even solve simple errors. It was disheartening to see students wandering through blogs for over an hour on problems that could be solved with just 10 minutes of proper study.

At that moment, I made a decision.

"I need to properly teach students how Git works!"

After six months of research, I developed a diagram that makes it easy to understand how Git works in just 10 minutes, and turned it into lecture material.

"Will this diagram really be easy to understand?"
"Can it sufficiently explain all cases?"
"Can it solve the errors students face?"

While answering these questions myself, I revised and revised the diagrams. After drawing so many diagrams that my iPad note-taking app slowed down, I was finally able to complete a clear and easy-to-understand final diagram.

After that, when I taught Git using those diagrams, the students' reactions were truly amazing.

💬 "I've taken Git courses several times, but I learned the most in this one hour!"
💬 "This is the clearest Git explanation I've ever heard. Really."
💬 "Ah, now I get it!"

Seeing students become proficient with Git in just 1 hour gave me great satisfaction.

Have you taken Git courses before but still find it confusing?
Have you felt frustrated because troubleshooting errors is difficult?
Are you wasting time searching for solutions on blogs?

Then you've come to the right place. 👏

After taking this course, all your worries about Git will completely disappear. I am 100% confident. If you don't see the expected results, I will give you a full refund.
