How to Use GitHub Desktop for Beginner

1. Introduction

GitHub Desktop is a user-friendly graphical interface that simplifies working with Git and GitHub repositories. It allows users to manage repositories, perform commits, resolve conflicts, and synchronize code with GitHub—all without using the command line.

Why It Matters

For beginners, the Git command-line interface can be intimidating. GitHub Desktop bridges that gap by providing a visual and intuitive way to use Git and GitHub. It is especially helpful for those new to version control, enabling them to focus on collaboration and code without needing deep technical knowledge of Git commands.

Who This Guide Is For

  • Beginner developers learning Git and GitHub
  • Students working on coding assignments or group projects
  • Non-technical contributors (e.g., designers, technical writers) collaborating on documentation or files in GitHub
  • Teams looking for a simplified Git GUI to ease onboarding

2. Key Terminology

Term Description
Repository (Repo) A storage space for your project code and files.
Clone Creating a local copy of a remote repository.
Commit A snapshot of changes made to files.
Push Sending local commits to a remote repository (GitHub).
Pull Fetching changes from the remote repository to your local machine.
Branch An independent line of development in a repository.
Merge Combining changes from one branch into another.
Pull Request (PR) A request to merge changes into a branch, often reviewed by others before approval.

3. Technical Overview

GitHub Desktop is built using Electron, a framework that allows cross-platform desktop apps using web technologies. It acts as a wrapper around Git, providing a graphical interface to Git operations.

Step 3: Clone a Repository

  • In GitHub Desktop: File > Clone repository
  • Select a repo from your GitHub account or enter a URL
  • Choose a local path to save it
  • Click Clone

Step 4: Make Changes Locally

  • Open the cloned folder in your editor (e.g., VS Code)
  • Modify files (e.g., README.md)
  • Save the changes

Step 5: Commit Changes

  • Return to GitHub Desktop
  • View changes under the Changes tab
  • Add a summary message
  • Click Commit to main (or your current branch)

Step 6: Push Changes to GitHub

  • Click Push origin (top right)
  • Your changes are now live on GitHub

Step 7: Pull Remote Changes

  • Click Fetch origin
  • Then click Pull origin to sync with the remote

Step 8: Create and Merge Branches (Optional)

To create a new branch:

  • Click the branch dropdown
  • Click New Branch, name it, and click Create Branch

To merge branches:

  • Switch to the main branch
  • Click Branch > Merge into Current Branch
  • Select the feature branch

5. Best Practices

  • Commit often: Keep commits small and focused
  • Use clear commit messages: Explain what & why
  • Pull before push: Prevent merge conflicts
  • Don’t commit secrets: Avoid pushing passwords or keys
  • Use branches: Keep features/fixes isolated
  • Check the diff before committing: Avoid mistakes

6. Common Issues & Troubleshooting

Issue Solution
Cannot push changes Ensure you're authenticated and have permission
Merge conflicts Use GitHub Desktop’s visual tool or resolve in an editor
Repo not showing up Make sure you're logged into the correct GitHub account
Changes not appearing Ensure files are saved and in the cloned repo
