Getting Started with GitHub

Welcome to your Skills exercise! 👋 If you are new to GitHub, you might find your fellow developers use issues to organize their work and collaborate. We will do the same! That's another lesson, but today, we will introduce you to the basics. GitHub is a web-based platform for version control and collaboration, allowing developers to manage and track changes to their code. It's a crucial tool for any developer, and understanding its basics is essential for success in the industry.

Why GitHub?

GitHub is a popular platform used by millions of developers worldwide. It provides a centralized location for developers to store and manage their code, making it easier to collaborate with others and track changes. With GitHub, developers can create repositories, manage branches, and collaborate with others in real-time. GitHub's features include:

  • Version control: GitHub allows developers to track changes to their code and revert to previous versions if needed.
  • Collaboration: GitHub enables multiple developers to work on the same project simultaneously, making it easier to collaborate and manage large teams.
  • Open-source: GitHub is home to many open-source projects, allowing developers to contribute to and learn from others.

Creating a GitHub Account

To get started with GitHub, you need to create an account. Follow these steps:

  1. Go to GitHub.com: Navigate to github.com and click on the "Sign up" button.
  2. Choose a username: Select a unique username that will represent you on GitHub.
  3. Create a password: Choose a strong password that meets GitHub's requirements.
  4. Add your email: Enter your email address to receive notifications and updates from GitHub.
  5. Verify your email: GitHub will send a verification email to your email address. Click on the link to verify your email address.

Understanding GitHub Terminology

Before we dive deeper into GitHub, let's understand some basic terminology:

  • Repository (or repo): A repository is a central location for your code, where you can store and manage your files.
  • Branch: A branch is a separate line of development in your repository, allowing you to work on different features or versions of your code.
  • Commit: A commit is a snapshot of your code at a particular point in time, allowing you to track changes and revert to previous versions.
  • Pull request: A pull request is a request to merge changes from one branch into another, allowing you to collaborate with others and review changes.

Creating a Repository

Now that you have a GitHub account, let's create a repository. Follow these steps:

  1. Log in to GitHub: Navigate to github.com and log in to your account.
  2. Click on the "+" button: Click on the "+" button in the top-right corner of the screen to create a new repository.
  3. Enter repository details: Enter a name for your repository, a description, and choose a license.
  4. Create the repository: Click on the "Create repository" button to create your repository.

Now that have a repository, let's commit some changes. Follow these steps:

  1. Navigate to your repository: Navigate to your repository on GitHub.
  2. Click on the "Code" button: Click on the "Code" button to view your repository's code.
  3. Make changes: Make some changes to your code, such as adding a new file or modifying an existing one.
  4. Commit changes: Click on the "Commit changes" button to commit your changes.

Pushing Changes

Now that you have committed changes, let's push them to GitHub. Follow these steps:

  1. Navigate to your repository: Navigate to your repository on GitHub.
  2. Click on the "Code" button: Click on the "Code" button to view your repository's code.
  3. Click on the "Push" button: Click on the "Push" button to push your changes to GitHub.
