How to Use Git with GitHub?

Git and GitHub are powerful tools for version control and collaboration, widely used in software development and project management. While Git is the version control system that tracks changes in your project, GitHub provides a platform to store, share, and collaborate on these changes with others.

This blog will guide you through the essential steps to get started with Git and GitHub, from installation to basic workflows.

What is Git and GitHub?

Git

Git is a distributed version control system that allows you to track changes to your files, collaborate with others, and maintain a complete history of your project.

GitHub

GitHub is a cloud-based platform that integrates with Git, allowing you to host repositories, manage pull requests, and collaborate with others seamlessly.

Step 3: Clone a Repository from GitHub

To work with an existing GitHub repository on your local machine:

1. Find the Repository:

• Navigate to the desired repository on GitHub.
• Click the green Code button.
• Copy the HTTPS or SSH URL.

Step 4: Create and Push Changes to GitHub

1. Make Changes Locally

Modify files in the repository using your preferred text editor or IDE.

2. Stage the Changes

Add the modified files to the staging area:

git add .

3. Commit the Changes

Record the changes in your local Git history:

git commit -m "Your commit message"

4. Push the Changes to GitHub

Upload your changes to the remote repository:

git push origin main

Replace main with the branch name if it’s different.

Step 5: Collaborate Using Pull Requests

1. Create a New Branch:

   git checkout -b new-feature

2. Push the Branch to GitHub:

   git push origin new-feature

3. Open a Pull Request:

• Navigate to the repository on GitHub.
• Click Pull Requests > New Pull Request.
• Select the branch you created and submit the pull request.

Step 6: Sync Changes from GitHub

To ensure your local repository is up-to-date with the remote repository:

1. Fetch updates:

   git fetch

2. Merge updates:

   git merge origin/main

Replace main with your branch name if needed.

3. Alternatively, use:

   git pull
