Welcome to Your Skills Exercise!

👋 Hey there, SaiKrishnaAleti! 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:

  • Repositories: A repository is a collection of files and folders that make up a project. You can think of it as a digital file cabinet where you store all the files related to your project.
  • Commits: A commit is a snapshot of your code at a particular point in time. When you make changes to your code, you create a new commit that captures the changes.
  • Branches: A branch is a separate line of development in your repository. You can use branches to work on new features or bug fixes without affecting the main codebase.
  • Pull Requests: A pull request is a request to merge changes from one branch into another. It's a way to review and discuss changes before they are merged into the main codebase.

Creating a GitHub Account

To get started with GitHub, you 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.

Creating a New Repository

Once you have created your GitHub account, you can create a new repository. Here's how:

  1. Log in to your GitHub account.
  2. Click on the "+" button in the top right corner of the screen.
  3. Select "New repository" from the dropdown menu.
  4. Enter a name for your repository and a brief description.
  5. Choose whether you want to make your repository public or private.
  6. Click on the "Create repository" button.

Committing Changes

Once you have created your repository, you can start committing changes. Here's how:

  1. Make changes to your code.
  2. Open the terminal and navigate to your repository.
  3. Type git add . to stage all changes.
  4. Type git commit -m "Your commit message" to commit the changes.
  5. Type git push origin master to push the changes to the remote repository.

Pulling Changes

If someone else has made changes to your repository, you can pull those changes using the following steps:

  1. Open the terminal and navigate to your repository.
  2. Type git pull origin master to pull the changes from the remote repository.
  3. Review the changes and merge them into your local repository.

Conclusion

In this exercise, we introduced you to the basics of GitHub. We covered what GitHub is, how to create a GitHub account, how to create a new repository, how to commit changes, and how to pull changes. We hope this exercise has given you a good understanding of the basics of GitHub and how to use it to collaborate with others.

What's Next?

In the next exercise, we will cover how to use issues to organize your work and collaborate with others. We will also cover how to use branches to work on new features or bug fixes without affecting the main codebase.

Tips and Tricks

  • Always use a clear and descriptive commit message.
  • Use branches to work on new features or bug fixes without affecting the main codebase.
  • Use pull requests to review and discuss changes before they are merged into the main codebase.
  • Always push your changes to the remote repository after committing them.

  1. Open the terminal and navigate to your repository.
  2. Type git pull origin master to pull the changes from the remote repository.
  3. Review the changes and merge them into your local repository.

Q: What is the difference between a public and private repository?

A: A public repository is visible to everyone on the internet, while a private repository is only visible to authorized users. If you want to collaborate with others on a project, you should use a public repository. If you want to keep your project private, you should use a private repository.

Q: How do I create a new branch in my repository?

A: To create a new branch in your repository, follow these steps:

  1. Open the terminal and navigate to your repository.
  2. Type git branch <branch-name> to create a new branch.

Q: How do I merge a branch into the main codebase?

A: To merge a into the main codebase, follow these steps:

  1. Open the terminal and navigate to your repository.
  2. Type git checkout master to switch to the main codebase.
  3. Type git merge <branch-name> to merge the branch into the main codebase.

Q: What is a fork?

A: A fork is a copy of a repository that you create in your own account. You can use a fork to make changes to a repository without affecting the original repository.

Q: How do I create a fork of a repository?

A: To create a fork of a repository, follow these steps:

  1. Open the repository you want to fork.
