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

Step by step from the fundamentals

Git vs GitHub❓

💻 Git

Git is a program that manages code versions. 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 like baseball and soccer are different, Git and GitHub are also different from each other. Git is a tool for version control, while GitHub is a space where you can store those versions. That's why GitHub is often compared to Google Drive or Dropbox.

Git & GitHub, learn it properly all at once.

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

Target Audience

❓ With Git tutorials overflowing everywhere, why was 근본깃 created?

While working as a programming instructor, I realized one thing. The fact that many students only memorize Git commands without properly understanding how they work. As a result, they couldn't use Git efficiently and often encountered situations where they couldn't even solve simple errors. It was heartbreaking 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 up my mind.

"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 materials.

"Will this diagram be really easy to understand?"
"Will I be able to explain all the cases sufficiently?"
"Will I be able to solve the errors that students face?"

By answering these questions myself, I revised and re-revised the diagrams. After drawing countless diagrams to the point where my iPad note-taking app became sluggish, I was finally able to complete a clear and easy-to-understand final diagram.

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

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

Seeing students become proficient with Git in just one hour gave me great satisfaction as well.

Have you taken Git lectures but still find it confusing?
Do you feel 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, your worries about Git will completely disappear. I am 100% confident. If you don't see the expected results, I will provide a full refund.
