Github Branching, Pull Requests and Merging for Testing New Features

Explain github branching so an 8 year old can understand it

ChatGPT said:

Okay, imagine this:

You and your friends are building a big LEGO castle together. The castle is the main project (like the main branch in GitHub).

But one day, you want to try building a cool new tower for the castle. Instead of changing the real castle right away, you grab some extra LEGO pieces and build your tower on the side. That’s called making a branch — it’s like saying:

👉 “I’m going to work on my own version without breaking the real castle.”

Now:

  • If the tower looks awesome, you can merge it back into the main castle so everyone can enjoy it.

  • If the tower is wobbly or silly, you can just throw it away, and the main castle is still safe.

So branching is just a safe way to try new ideas without messing up the original project.

Would you like me to make a little drawing/diagram to show this with castles or LEGOs?

LEGO Story (easy to understand) 🎲

Imagine you and your friends are building a big LEGO castle together. The castle is the main project — like the main branch in GitHub.

One day you want to try a cool new tower. Instead of changing the real castle, you grab extra LEGO pieces and build your tower on the side. That’s a branch — a safe place to try things without breaking the castle.

  • If the tower is awesome: merge it into the main castle so everyone can enjoy it.
  • If the tower is wobbly: throw it away — the main castle stays safe.

Commands & Workflow — From LEGO → Git (step-by-step) ⚙️

🏰 Main castle = main
This is your primary branch where stable code lives.
🧱 Make your own tower = create & switch to a new branch
git checkout -b my-tower
Creates a branch named my-tower and switches you to it.
🛠️ Build your tower = stage & commit changes
# Stage your changes (save your LEGO steps)
git add .

# Commit with a message (lock that step in)
git commit -m "Built a cool tower"
Use clear commit messages so your friends know what you changed.
🌐 Share with friends = push branch to GitHub
git push origin my-tower
Now your branch is on GitHub and others can review it.
🏰 Bring your tower back = Pull Request (PR) & Merge
  1. Open a Pull Request on GitHub — ask your team to review.
  2. Discuss and fix any feedback (push more commits to the same branch).
  3. When approved, click Merge to add it to main.
PRs are great for code review and catching issues before merging.
❌ Throw away a bad tower = delete the branch
# Delete local branch (after merge or if you don't need it)
git branch -d my-tower

# If branch wasn't merged and you want to force delete:
git branch -D my-tower

# Delete remote branch (on GitHub)
git push origin --delete my-tower
Deleting keeps the repo tidy.
⚡ Full workflow recap
1. Start from main.
2. git checkout -b new-idea → make a branch.
3. Do work → git add . + git commit -m "msg".
4. git push origin new-idea → share on GitHub.
5. Open a Pull Request → review → merge or delete.

🌟 GitHub Branching & Pull Requests — LEGO Style

Imagine you're building a big LEGO castle with friends. The main castle is the main branch. When you want to try a new tower, you build it on the side — that's a branch. This post shows the full workflow (commands + GitHub steps) in one neat code-friendly snippet. 🧱🏰

1) Create a branch — grab your LEGO pieces 🧩

Make a new branch and switch to it (you’re starting your own tower experiment). 


git checkout -b my-tower

2) Build (make changes) — snap bricks in place 🛠️

Save your steps locally with git add and git commit. 


git add .
git commit -m "added tower"

3) Share your branch on GitHub — show your friends 🌐

Push your branch up so others can see it on GitHub. 


git push origin my-tower

4) Create a Pull Request (PR) — ask to add the tower ✉️

On GitHub, a Pull Request is how you ask: “Can we add my tower to the castle?” Steps on the website:

  1. Go to your repository.
  2. Click Compare & pull request (or go to Pull Requests → New pull request).
  3. Pick your branch (my-tower) and compare to main.
  4. Add a title and description — explain what you changed.
  5. Click Create pull request.

5) Review & Merge — add the tower to the castle ✅

Once the PR looks good, merge it so the main castle gets your tower. On GitHub:

  1. Open the pull request page.
  2. Click the green Merge pull request button.
  3. Click Confirm merge.

6) Clean up — throw away extra LEGO if you’re done 🧹

After merging, delete the branch on GitHub and clean it up locally. 


# On GitHub: click "Delete branch" in the PR UI.

# Locally:
git checkout main
git pull
git branch -d my-tower

Quick Workflow Summary 🔁

Steps: git checkout -b new-idea git add . git commit -m "..." git push origin new-idea Create PR → Review → Merge

✨ Tip: Branches are safe experiments — try things, show your friends with a PR, then merge if it’s great. If not, delete it and the main castle stays perfect.

🧱 Merge Locally — A friendly guide (LEGO analogy + commands)

Think of your project as a big LEGO castle. Branches are the extra towers you build on the side. Merging locally is when you snap your tower onto the castle yourself — no website needed.

🔧 Local Merge Steps

1. Make sure you’re on the main branch 
git checkout main

👉 You’re standing at the real castle.

2. Update main (if working with others) 
git pull origin main

👉 Make sure your castle is the latest before attaching anything.

3. Merge your branch into main 
git merge my-tower

👉 This snaps your tower onto the castle. If no conflicts — Git applies the changes. If conflicts — you’ll fix them before continuing.

4. Push changes back to GitHub (optional) 
git push origin main

👉 Let others see the new castle + tower online.

5. Clean up your branch (optional) 
git branch -d my-tower

👉 Toss the extra LEGO pieces since the tower’s already attached.

⚡ Quick example (one block you can copy)

git checkout main
git pull origin main
git merge my-tower
git push origin main
git branch -d my-tower

🚧 Merge conflicts — what to expect

If two people changed the same LEGO spot (file lines) Git can’t decide which piece to use. You’ll see markers in the file like <<<<<<< and >>>>>>> . Open the file, choose which parts to keep (or combine them), remove the markers, then: 

git add 
git commit -m "Resolve merge conflict in <file>"
git push origin main

Tip: Use a visual merge tool (VS Code, GitKraken, Meld) if the conflict feels messy. 🛠️

Summary: switch to main → pull → merge branch → push → delete branch. Simple, safe, and great for teamwork. 🎉
