In the upper-right corner of any page, select your profile photo, then click settings. In the "access" section of the sidebar, click organizations.

Setting Up Git on Your Local Machine

Getting Git set up on your local machine is the first step to start using GitHub effectively. Let’s walk through the process step-by-step.

Installing Git

First things first, you need to install Git on your computer. If you’re on Windows, download the installer from the official Git website and follow the setup instructions. For Ubuntu users, open your terminal and run:

sudo apt install git

This command will use the apt package management tools to update your local package index and install Git. If you’re on Mac, you can use Homebrew:

brew install git

Configuring Git with Your Username and Email

Once Git is installed, you need to configure it with your username and email. This information will be associated with your commits. Open your terminal and type the following commands:

git config --global user.name "Your Name"
git config --global user.email "your.email@example.com"

You can verify your settings with:

git config --global --list

Generating SSH Keys for Authentication

To securely connect to GitHub, you’ll need to generate SSH keys. This step is crucial for authenticating your identity. In your terminal, type:

ssh-keygen -t rsa -b 4096 -C "your.email@example.com"

Follow the prompts to save the key. Once generated, add the SSH key to the ssh-agent:

ssh-add ~/.ssh/id_rsa

Finally, copy the SSH key to your clipboard and add it to your GitHub account. You can find the key with:

cat ~/.ssh/id_rsa.pub

And that’s it! You’re all set up to start using Git on your local machine.

Creating and Managing Repositories

Creating a New Repository

A repository is like a folder for your project. You can have any number of public and private repositories in your personal account. Repositories can contain folders and files, images, videos, spreadsheets, and data sets, as well as the revision history for all files in the repository. For more information, see "About repositories."

When you create a new repository, you should initialize the repository with a README file to let people know about your project. For more information, see "[Creating a new repository](https://docs.github.com/enterprise-server@3.14/repositories/creating-and-managing-repositories/creating-a-repository-from-a-template)."

Cloning a Repository

You can clone an existing repository from GitHub to your local computer, making it easier to add or remove files, fix merge conflicts, or make complex commits. Cloning a repository pulls down a full copy of all the repository data that GitHub has at that point in time, including all versions of every file and folder for the project. For more information, see "Cloning a repository."

Managing Repository Settings

As the owner of a repository you can configure several settings, including the repository’s visibility, topics, and social media preview. For more information, see "Managing your repository’s settings and features."

Understanding GitHub Workflow

Branching Strategies

Branching is a key part of working with GitHub. It allows you to work on different features or fixes without affecting the main codebase. Create a new branch for each feature or bug fix you work on. This keeps your main branch clean and stable.

Making Commits

Commits are snapshots of your project at a specific point in time. They help you keep track of changes and revert back if needed. Make sure your commit messages are clear and descriptive. This will help you and others understand what changes were made.

Pull Requests and Code Reviews

Pull requests are a way to propose changes to the codebase. They allow others to review your changes before they are merged. This is a great way to ensure code quality and catch any potential issues. When creating a pull request, provide a clear description of what changes were made and why.

Remember, a well-documented pull request can save a lot of time during the review process.

Here’s a quick overview of the GitHub workflow:

1. Create a branch for your feature or bug fix.
2. Make commits to your branch with clear messages.
3. Open a pull request to propose your changes.
4. Request a code review from your team.
5. Merge the pull request once it’s approved.

By following these steps, you can ensure a smooth and efficient workflow on GitHub.

Collaborating on GitHub Projects

Forking Repositories

Forking a repository is like making a copy of someone else’s project. This allows you to make changes without affecting the original. Most commonly, forks are used to propose changes or to use someone else’s project as a starting point for your own idea.

Submitting Pull Requests

Once you’ve made changes in your forked repository, you can submit a pull request to propose these changes to the original project. This is a key part of collaboration on GitHub. You can create an issue or pull request to propose and collaborate on changes to a repository.

Reviewing and Merging Pull Requests

After a pull request is submitted, it needs to be reviewed. This is where code reviews come in. Collaborators can comment on the changes, suggest improvements, and approve the pull request. Once approved, the changes can be merged into the main project. This process ensures that the project maintains high quality and that all changes are vetted before being included.

Exploring GitHub Features

Using GitHub Issues

GitHub Issues is a powerful tool for tracking tasks, enhancements, and bugs for your projects. You can create new issues, assign them to team members, and track their progress. It’s a great way to keep your project organized and on track.

Managing Projects with GitHub Projects

GitHub Projects allows you to organize and prioritize your work. You can create project boards to visualize your tasks and move them through different stages. This feature is especially useful for larger teams and complex projects.

Utilizing GitHub Actions for Automation

GitHub Actions lets you automate your workflows directly from your GitHub repository. You can set up continuous integration and continuous deployment (CI/CD) pipelines, automate testing, and more. This feature helps you save time and reduce errors by automating repetitive tasks.

Keep exploring GitHub’s features to make the most out of your projects and improve your workflow efficiency.

Integrating GitHub with Other Tools

Integrating GitHub with other tools can supercharge your workflow and make your development process smoother. Let’s dive into how you can connect GitHub to your favorite tools and services.

Securing Your GitHub Account

Setting Up Two-Factor Authentication

To keep your GitHub account safe, setting up two-factor authentication (2FA) is a must. After you sign in to GitHub using your password, you’ll need to provide an authentication code or use a security key to perform 2FA. This extra step ensures that even if someone gets your password, they can’t access your account without the second factor.

Managing SSH and GPG Keys

SSH and GPG keys add another layer of security to your GitHub activities. You can securely access your account’s resources by authenticating to GitHub using these keys. After securing your account with a security key, there’s more you can do with them. You can also digitally sign your Git commits using a GPG key stored on your device.

Understanding Security Alerts

GitHub is committed to keeping our platform secure and enabling developers to secure their accounts. One way we’re doing that is by helping more developers understand security alerts. These alerts notify you of vulnerabilities in your repositories, allowing you to take action quickly to fix them.

Keeping your GitHub account secure is not just about protecting your code, but also about safeguarding your entire development environment.

Leveraging GitHub Community and Resources

Joining GitHub Discussions

GitHub Discussions is a fantastic way to enhance collaboration and share information. Widely used by open-source communities and development teams, it helps build a stronger, more connected community. You can ask questions, share ideas, and get feedback from other developers.

Contributing to Open Source Projects

Contributing to open source projects is a rewarding way to learn, teach, and build experience. You can find projects that match your interests and skills. This is a great way to make software development more accessible, inclusive, and sustainable.

Utilizing GitHub Learning Lab

Advanced Git Techniques

Rebasing vs. Merging

When working with Git, you’ll often need to integrate changes from one branch into another. This can be done using either rebasing or merging. Rebasing rewrites the commit history, making it appear as if all changes were made sequentially. This can make the project history cleaner. On the other hand, merging preserves the original commit history and creates a new commit that combines the changes from both branches.

Cherry-Picking Commits

Cherry-picking allows you to apply a specific commit from one branch to another. This is useful when you need a particular change without merging the entire branch. To cherry-pick a commit, use the command git cherry-pick <commit-hash>. This will apply the changes from the specified commit to your current branch.

Handling Merge Conflicts

Merge conflicts occur when changes from different branches conflict with each other. Git will mark the conflicting areas in the files, and you’ll need to resolve these conflicts manually. After resolving the conflicts, you can complete the merge by committing the changes. It’s a good idea to frequently pull changes from the remote repository to minimize conflicts.

The more you use Git, the more comfortable you’ll get with it. Practice makes perfect, so don’t hesitate to experiment with these advanced techniques.

Archiving and Deleting Repositories

Archiving a Repository

Archiving a repository is a great way to preserve your work without actively maintaining it. When you archive a repository, its issues, pull requests, and code become read-only. This means no more changes can be made, but everything is still accessible for reference.

To archive a repository:

1. Navigate to the repository you want to archive.
2. Click on the Settings tab.
3. Scroll down to the Danger Zone section.
4. Click on Archive this repository.
5. Confirm by typing the repository name and clicking I understand, archive this repository.

Archiving is perfect for projects that are no longer active but still valuable for future reference.

Deleting a Repository

Deleting a repository is a permanent action, so make sure you really want to do this. Once deleted, all the data, including issues, pull requests, and commits, will be gone forever.

To delete a repository:

1. Go to the repository you wish to delete.
2. Click on the Settings tab.
3. Scroll down to the Danger Zone section.
4. Click on Delete this repository.
5. Confirm by typing the repository name and clicking I understand the consequences, delete this repository.

If your repository is unavailable due to a DMCA takedown, you won’t be able to access the settings directly. Follow the specific steps provided by GitHub to delete the repository.

Restoring Deleted Repositories

Accidentally deleted a repository? No worries, you can restore it within 90 days of deletion. After that, it’s gone for good.

To restore a deleted repository:

1. Navigate to your GitHub profile.
2. Click on Repositories.
3. Find the Deleted repositories section at the bottom.
4. Click on the repository you want to restore.
5. Click Restore to bring it back.

Restoring a repository is a lifesaver if you accidentally delete something important. Just make sure to act quickly!

Using GitHub for Documentation

Creating a README File

A README file is the first thing people see when they visit your repository. It’s your chance to make a great first impression. Make sure to include a clear and concise description of your project. You can also add installation instructions, usage examples, and any other information that will help users understand and use your project.

Using GitHub Pages

GitHub Pages allows you to create a website for your project directly from your repository. It’s perfect for hosting project documentation, portfolios, or any static content. You can use GitHub Actions to build and deploy your site automatically.
