What is GitHub?
GitHub is a web-based platform that uses Git for version control and offers features to facilitate collaboration on software development projects. It hosts your Git repositories and provides a user-friendly interface for managing your projects, collaborating with others, and tracking changes.
Key Features of GitHub:
- Repositories: Store your project files and version history.
- Branches: Allow you to work on different features or versions of a project simultaneously.
- Pull Requests: Facilitate code review and collaboration by proposing changes to be merged into the main project.
- Issues: Track bugs, enhancements, and tasks.
- Collaborators: Invite others to work on your project with different levels of access.
- GitHub Actions: Automate workflows, such as testing and deployment.
