Git & GitHub, Step by Step from the Principles - Fundamental Git [Basics]

Step by step from the principle

Git vs GitHub ❓

💻 Git

Git is a program that manages the version of code. Just like creating SAVE points in a game, you can create SAVE points in your code through Git and roll back to a desired point in time . In addition, it helps multiple colleagues work on a project at the same time by utilizing a powerful function called 'branch'.

🌐 GitHub

First, it should be noted that Git and GitHub are completely different concepts. Just as baseball and football are different, Git and GitHub are different. Git is a version control tool, and GitHub is a place to store those versions. That’s why GitHub is often compared to Google Drive or Dropbox .

Learn Git & GitHub properly at once.

Everyone will agree that Git is important. No matter what we make, we will always use Git. Therefore, we must know Git properly. If you simply memorize commands like a machine, you will end up wandering around looking for blogs. Learn from the basics to the principles at once. I can say with certainty that after taking the 'Fundamental Git' course, you will be able to solve 99% of errors on your own.

Target audience

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

As a programming instructor, I realized one thing. Many students only memorize Git commands and do not properly understand how they work . As a result, I often encountered situations where they could not handle Git efficiently and could not even solve simple errors . It was heartbreaking to see students wandering around blogs for over an hour for problems that could be solved with just 10 minutes of proper study.

At that moment, I decided.

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

After half a year of research, I developed a diagram that makes it easy to understand how Git works in just 10 minutes , and made it into teaching material.

"Is this picture really easy to understand?"
"Can all cases be adequately explained?"
"Can we solve the errors students face?"

As I answered these questions, I revised and revised the drawing. After drawing so many drawings that the iPad's note-taking app slowed down, I was finally able to complete the final drawing , which was clear and easy to understand.

After that, when I taught Git with that picture, the students' reactions were truly amazing.

💬 "I've taken Git classes many times, but this is the one hour I learned the most!"
💬 "This is the most understandable explanation of Git I've ever heard. Seriously."
💬 "Ah, now I get it!"

It was very rewarding to see my students become proficient at using Git in just one hour.

Have you taken a Git course but are still confused?
Are you feeling frustrated because you have difficulty troubleshooting errors?
Are you wasting your time searching for solutions on blogs?

If so, you've come to the right place. 👏

If you take this course, your worries about Git will completely disappear . I am 100% sure . If you do not see the expected results, I will give you a full refund .
