From Code to Performance

Hello World on Github

The Hello World tutorial teaches the workflow you'll use daily: repositories, branches, commits, and pull requests.

Concepts Introduced

• Repository: A project container for files + history
• Branch: A parallel version of the repository
• Commit: A snapshot of changes made to the files
• Pull Request (PR): A request to merge changes from one branch to another

Hands-On: Hello World Tutorials

1. Create a Repository
• Click + "New Repository" on your GitHub dashboard.
• Name it hello-world
• Add a README.md file (this serves as your project;s description).
2. Create a Branch"
• By default, your repo has one branch: main.
• Create a branch called readme-edits.
• This allows you to test changes without affecting main..
3. Make Changes and Commit Changes
• Edit the README.md by adding a line like: Hello, World! This is my first commit.
• Save and commit your changes with a message: "Added introduction to README".
4. Open a Pull Request (PR)
• Go to the "Pull requests" tab in your repository.
• Click "New pull request".
• Select your readme-edits branch as the compare branch.
• Click "Create pull request".
5. Review and Merge the Pull Request
• Once satifsied, click Merge Pull Request
• You can now delete the branch readme-edits since its changes are in main.
