GitHub

1. Version Control: GitHub uses the Git version control system, allowing developers to track changes to code, collaborate on modifications, and manage different versions of their projects.
2. Repositories: Repositories (repos) are containers for projects. Each repository stores code, documentation, and other project files. Repositories can be public (open to the community) or private (restricted to authorized users).
3. Pull Requests: Pull requests allow developers to propose changes to a repository's codebase. They provide a way for team members to review, discuss, and collaborate on code changes before merging them into the main codebase.
4. Issues and Bug Tracking: GitHub provides an issue tracker for reporting, managing, and discussing bugs, feature requests, and other project-related tasks.
5. Branches: Developers can create branches to work on features or bug fixes independently from the main codebase. Branches can be merged back into the main branch (often "master" or "main") when the changes are ready.
6. Collaboration: GitHub facilitates collaboration through features like code reviews, inline comments, and discussions on issues and pull requests.
7. Continuous Integration: GitHub supports integration with various continuous integration (CI) services, enabling automated testing and deployment of code changes.
8. GitHub Actions: GitHub Actions provides built-in CI/CD capabilities directly within GitHub, allowing you to automate workflows, build, test, and deploy applications.
9. Projects and Boards: GitHub provides tools for creating project boards, tracking tasks, and visualizing the progress of work.
10. Wikis and Documentation: Repositories can include documentation, wikis, and README files to provide information about the project and how to contribute.

GitHub has become a central hub for open-source and private software development, enabling developers to collaborate on projects, share knowledge, and build software more efficiently. It is widely used by individual developers, organizations, and communities to manage code, streamline workflows, and contribute to a wide range of projects.
