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.

What is GitHub?

GitHub is a web-based platform for version control and collaboration on software development projects. It allows developers to store and manage their code in a centralized location, making it easier to collaborate with others and track changes to the codebase. GitHub provides a range of features, including:

  • Version control: GitHub allows developers to track changes to their codebase over time, making it easier to identify and fix errors.
  • Collaboration: GitHub enables multiple developers to work on the same project simultaneously, making it easier to collaborate and share code.
  • Open-source: GitHub provides a platform for open-source projects, allowing developers to share their code with others and collaborate on projects.

Creating a GitHub Account

To get started with GitHub, you will need to create an account. Here's how:

  1. Go to the GitHub website (www.github.com) and click on the "Sign up" button.
  2. Enter your email address, username, and password.
  3. Fill out the required information, including your name and location.
  4. Click on the "Create account" button.

Understanding GitHub Terminology

Before we dive into the exercise, let's cover some basic GitHub terminology:

  • Repository (or repo): A repository is a collection of files and folders that make up a project.
  • Branch: A branch is a separate line of development in a repository.
  • Commit: A commit is a snapshot of changes made to a repository.
  • Pull request: A pull request is a request to merge changes from one branch into another.

  3. Select "New repository" from the dropdown menu.
  4. Enter a name for your repository and a brief description.
  5. Click on the "Create repository" button.

Step 2: Initialize a Repository

  1. Click on the "Code" button in the top-right corner of the screen.
  2. Select "Initialize this repository" from the dropdown menu.
  3. Follow the prompts to initialize your repository.

Step 3: Create a New File

  1. Click on the "New file" button in the top-right corner of the screen.
  2. Enter a name for your file and a brief description.
  3. Click on the "Create file" button.

Step 4: Commit Your Changes

  1. Click on the "Commit" button in the top-right corner of the screen.
  2. Enter a commit message and click on the "Commit" button.

Exercise: Collaborating with Others

Step 1: Create a New Branch

  1. Click on the "New branch" button in the top-right corner of the screen.
  2. Enter a name for your branch and on the "Create branch" button.

Step 2: Make Changes to Your Branch

  1. Click on the "Edit" button next to your file.
  2. Make some changes to your file.
  3. Click on the "Commit" button.

Step 3: Create a Pull Request

  1. Click on the "New pull request" button in the top-right corner of the screen.
  2. Select the branch you want to merge into.
  3. Click on the "Create pull request" button.

Conclusion

Congratulations! You have completed the exercise and learned the basics of GitHub. You now know how to create a repository, initialize a repository, create a new file, commit your changes, create a new branch, make changes to your branch, and create a pull request.
