GitHub is a web-based platform used for version control and collaboration, allowing developers to manage and store their code in repositories. Here’s a brief overview of its key features and how to get started:
▎Key Features of GitHub
1.
Version Control: GitHub uses Git, a version control system that tracks changes in your code, allowing you to revert to previous versions if needed.
2.
Repositories: A repository (or repo) is where your project lives. It can contain files, folders, images, and the entire history of your project.
3.
Branches: Branching allows you to work on different versions of a project simultaneously. The default branch is usually called
main or
master.
4.
Pull Requests: A pull request (PR) is a way to propose changes to a repository. You can discuss and review changes before merging them into the main codebase.
5.
Issues: GitHub provides an issue tracker that allows you to manage bugs, feature requests, and other tasks related to your project.
6.
Collaboration: You can invite other developers to collaborate on your projects, making it easy to work in teams.
7.
GitHub Actions: This feature allows you to automate workflows directly in your GitHub repository, such as continuous integration and deployment (CI/CD).
8.
GitHub Pages: You can host static websites directly from your GitHub repositories.

6.
Stage and Commit Changes:
– Use
git add . to stage changes.
– Use
git commit -m "Your commit message" to commit your changes.
7.
Push Changes to GitHub:
– Use
git push origin main (or the name of your branch) to push your changes back to GitHub.
8.
Create a Pull Request:
– Go to your repository on GitHub.
– Click on "Pull requests" and then "New pull request" to propose merging changes from one branch into another.
9.
Collaborate:
– Invite collaborators by going to the "Settings" tab of your repository and adding their GitHub usernames under "Manage access."
