Git Maxing 101 Git, GitHub, GitHub Actions Three different things. People always confuse. Today, no more confuse. Developer write code. Live on laptop. Laptop only. Laptop die. Code die. Very sad. Git wake up. Git live on your machine. Git a terminal. You type commands. Code have history now. Every change saved. You break something, go back in time.

Old version still there. All this offline. No internet, No cloud, only Git. You want new feature? Make new branch. This also, Git. Still local. But code, still on laptop. Laptop die, code die. GitHub wake up. GitHub, not Git. GitHub, a place, a cloud location, a remote location. How they connect? This command is the bridge.

Now, local Git, know where cloud live. Git push, code go up. Code now, safe. Code now, everywhere. Now, many human work together. Human create new branches. Human cannot push branch to main. Main protected. Main sacred. Human open pull request. Pull request? GitHub thing, not git thing. Other human look. This line bad. Fix this.

You fix. Now merge? No. Human forget run test. Human always forget. Human is human. GitHub actions wake up. Actions live inside GitHub. It is a robot. How robot know what to do? You write one file. Robot read file. Robot, do exactly what file says. Robot, build app. Robot, run test. Robot, run scan.

Robot, never tired. Robot, never forget. Test pass, green. Merge allowed. Test fail, red. Merge blocked. Human, go fix. No bad code, reach main. Robot, protect the main branch. So remember, git, track history. Local, your machine. GitHub, post the copy. Cloud, shareable. GitHub Actions, runs the robot. automatic, tireless, three things, different jobs, good teamwork.
