Getting Started with GitHub

Welcome to GitHub! 👋 As a developer, you're likely familiar with the importance of collaboration and version control in software development. GitHub is a web-based platform that enables developers to host and review code, manage projects, and collaborate with others. In this exercise, we'll introduce you to the basics of GitHub and help you get started with using this powerful tool.

What is GitHub?

GitHub is a web-based platform that allows developers to host and review code, manage projects, and collaborate with others. It's a place where developers can share their code, get feedback, and work together on projects. GitHub is built on top of the Git version control system, which allows developers to track changes to their code over time.

Key Concepts in GitHub

Before we dive into the exercise, let's cover some key concepts in GitHub:

  • Repository (Repo): A repository is a central location where all the files for a project are stored. Think of it as a digital file cabinet where you can store and manage all the files related to a project.
  • Branch: A branch is a separate line of development in a repository. It allows developers to work on different features or versions of a project without affecting the main codebase.
  • Commit: A commit is a snapshot of changes made to a repository. It's like taking a photo of your code at a particular point in time.
  • Pull Request: A pull request is a request to merge changes from one branch into another. It's a way for developers to review and discuss changes before they're merged into the main codebase.

Step 1: Creating a GitHub Account

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

  1. Go to github.com and click on the "Sign up" button.
  2. Fill out the registration form with your email address, username, and password.
  3. Verify your email address by clicking on the link sent to you by GitHub.
  4. Set up your profile by adding a profile picture, bio, and other details.

Step 2: Creating a New Repository

Once you have a GitHub account, you can create a new repository. Follow these steps:

  1. Log in to your GitHub account and click on the "+" button in the top-right corner.
  2. Select "New repository" from the dropdown menu.
  3. Fill out the repository name, description, and other details.
  4. Choose a repository type (public or private) and select the license.
  5. Click on the "Create repository" button.

Step 3: Initializing a Git Repository

To use GitHub, you'll need to initialize a Git repository on your local machine. Follow these steps:

  1. Open a terminal or command prompt and navigate to the directory where you want to create your repository.
  2. Run the command git add . to stage all the files in the directory.
  3. Run the command git commit -m "Initial commit" to commit the changes.
  4. Run the command git remote add origin <repository-url> to link your local repository to the GitHub repository.
  5. Run command git push -u origin master to push the changes to GitHub.

Step 4: Creating a New Branch

To work on a new feature or version of a project, you'll need to create a new branch. Follow these steps:

  1. Run the command git branch <branch-name> to create a new branch.
  2. Run the command git checkout <branch-name> to switch to the new branch.
  3. Make changes to the code and commit them using git add and git commit.
  4. Run the command git push origin <branch-name> to push the changes to GitHub.

Step 5: Creating a Pull Request

To merge changes from one branch into another, you'll need to create a pull request. Follow these steps:

  1. Go to your GitHub repository and click on the "Pull requests" tab.
  2. Click on the "New pull request" button.
  3. Select the branch you want to merge into the main codebase.
  4. Fill out the pull request title and description.
  5. Click on the "Create pull request" button.

Conclusion

Congratulations! You've completed the exercise and learned the basics of GitHub. You now know how to create a GitHub account, create a new repository, initialize a Git repository, create a new branch, and create a pull request. Practice makes perfect, so be sure to try out these steps on your own project.
