Lesson: GitHub Repository Creation

🎯 Objective

Create a repository on GitHub and connect it to your local repository.

✅ Step 4: Create a Repository on GitHub

  1. Go to https://github.com and sign in.
  2. Click the + button in the top right and select New repository.

  3. Fill in:

    • Repository name: same as your folder (e.g., my-website)
    • Visibility: Public or Private
    • DO NOT initialize with a README (your local repo already has content)
  4. Click Create repository.

What happened? You just created a “remote” repository on GitHub’s servers. This is like creating a backup copy of your project that lives on the internet, separate from your local computer.

How to verify: After creating the repo, you should see a page with setup instructions. Look for a green “Code” button - this means your repository was created successfully. The URL should be something like https://github.com/YOUR-USERNAME/my-website.

GitHub will display instructions for adding a remote repository — you’ll use them next.

✅ Step 5: Connect Local Repo to GitHub

Back in the terminal, link your local repo to the GitHub repo. Replace YOUR-USERNAME and REPO-NAME with your info:

git remote add origin https://github.com/YOUR-USERNAME/REPO-NAME.git

What happened? You just told your local Git repository where to find its “remote” partner on GitHub. Think of it like setting up a phone number so your local repo can “call” the GitHub repo.

How to verify: Type git remote -v in your terminal. You should see the GitHub URL listed as “origin”.

Push your code to GitHub:

git push -u origin main

If main doesn’t exist yet, create it:

git branch -M main
git push -u origin main

What happened? You just sent all your local files and commits to GitHub! The -u flag sets up “upstream tracking” so future pushes know where to go.

How to verify: Go to your GitHub repository page in your browser. You should see your index.html and style.css files listed there. Also, type git status - you should see “Your branch is up to date with ‘origin/main’”.

✅ Summary

You learned how to:

Your local and remote repositories are now connected and synchronized!
