How does GitHub work?

GitHub is a web-based platform that allows users to store and manage their Git repositories online. Git is a version control system that helps developers track and manage changes to their code. GitHub provides a user interface that makes it easy to work with Git repositories and collaborate with other developers.

  1. Create a GitHub account and sign in.
  2. Create a new repository for your code, or clone an existing repository from someone else.
  3. Use Git to manage your code changes locally on your computer.
  4. Push your code changes to the repository on GitHub.
  5. Use the GitHub user interface to review and discuss your code changes with other developers.
  6. Merge your code changes into the main branch of the repository, or create a pull request if you want someone else to review and merge your changes.

GitHub also provides a range of features that make it easier to collaborate with others, such as the ability to create and manage issues, review code changes, and track the progress of projects.

It is a popular platform for open-source projects and is used by many companies and organizations for managing their code repositories and collaborating with developers.

What is Git?

Git is a version control system that allows developers to track changes to their codebase and collaborate with other developers on projects. It is particularly useful for coordinating work on projects that involve multiple people and for tracking the history of changes to a project. Git works by keeping track of changes to files in a project over time. When you make a change to a file, you can commit that change to the Git repository, which stores the change along with a message describing the change. This allows you to go back to previous versions of the project or to see exactly what changes were made between versions. Git also allows you to work on different versions of a project in parallel, called branches. You can create a new branch to make changes to a project without affecting the main version of the project, and then merge those changes back into the main version when they are ready.
Git is widely used by developers and is a key tool for collaborative software development. It is open source and available on most operating systems.
