Git and Github Explained

Hey there so you’ve been hearing about Git and GitHub...
Welcome to the world of version control — where collaboration meets backup, and coding becomes way less scary.

This isn’t your average tutorial. This is you learning Git the smart, beginner-friendly, not-so-boring way.

So... What Even Is Version Control?

Imagine writing an essay, then accidentally deleting half of it. Now imagine having a magic “undo” button — not just for the last change, but for every single change ever made. That’s version control.
It helps you:

• Track changes to your code over time
• Work in teams without fighting over one file
• Go back in time when you mess up (you will)
• Collaborate without chaos The tool we use for that? Git. And where we host our Git work? **GitHub. ##Git Basics Let’s not memorize commands — let’s understand what they do.

Command	Meaning
git init	"I'm starting a project"
git clone	"Copy this repo to my laptop"
git status	"What’s the situation with my files?"
git add	"I want to include this in the next save"
git commit -m "msg"	"Save this version with a message"
git push	"Upload my changes to GitHub"
git pull	"Download latest changes from GitHub"
git merge	"Combine this branch with another"

Forking

Forking is just a fancy way of saying:

“Hey, I want to make my own copy of this project so I can mess with it.”
It’s how you:

• Contribute to open source
• Experiment without wrecking the original
• Start customizing someone else’s code Go to a GitHub repo → Click Fork → It’s now yours. Remix it like it’s your favorite song

Collaboration

**With Git and GitHub, you can:

• Create branches to work on features
• Push your changes
• Pull others’ updates
• Review and merge work as a team Teamwork becomes less “he touched my code” and more “let’s build something amazing together”.

Pull Requests

A Pull Request (PR) is like submitting an assignment:

1. You fork → clone → make changes.
2. You push your changes.
3. You open a PR and say: "Hi maintainer, here’s what I changed and why."
4. They review it. You fix stuff. They merge it. You celebrate A PR isn’t just a request — it’s a conversation about code.

Merge Conflicts

**Merge conflicts happen when:

• You and someone else edit the same line in the same file. Git freaks out and marks the conflict like this:

bash
HEAD
Your changes
Other person's changes
other-branch

**Code Reviews

**
Pull Requests usually come with code reviews, which are:

• A chance to catch bugs before they grow up
• A way to learn cleaner, smarter code
• A form of teamwork (not judgement!)

Tip: Ask questions. Be kind. No one writes perfect code. Not even senior devs.

GitHub Issues

GitHub Issues are like a to-do list:

• Report bugs
• Request features
• Ask questions
• Organize tasks

You can label them, assign them, and even link them to pull requests. Organized code = happy devs.

Pushing Changes to GitHub

Once you’ve made some edits locally:

bash
git add .
git commit -m "Added something amazing"
git push origin your-branch
