What is GitHub?

I'm glad you asked! Many people come to GitHub because they want to contribute to open source ^📖 projects, or they're invited by teammates or classmates who use it for their projects. Why do people use GitHub for these projects?

At its heart, GitHub is a collaboration platform.

From software to legal documents, you can count on GitHub to help you do your best work with the collaboration and security tools your team needs. With GitHub, you can keep projects completely private, invite the world to collaborate, and streamline every step of your project.

GitHub is also a powerful version control tool.

GitHub uses Git ^📖, the most popular open source version control software, to track every contribution and contributor ^📖 to your project--so you know exactly where every line of code came from.

GitHub helps people do much more.

GitHub is used to build some of the most advanced technologies in the world. Whether you're visualizing data or building a new game, there's a whole community and set of tools on GitHub that can get you to the next step. This course starts with the basics, but we'll dig into the rest later!

More features

The video covered some of the most commonly-used features. Here are a few other items you can find in GitHub repositories:

• Project boards: Create Kanban-style task tracking board within GitHub
• Wiki: Create and store relevant project documentation
• Insights: View a drop-down menu that contains links to analytics tools for your repository including:
  • Pulse: Find information about the work that has been completed and the work that’s in-progress in this project dashboard
  • Graphs: Graphs provide a more granular view of the repository activity including who contributed to the repository, who forked it, and when they completed the work

Special Files

In the video you learned about a special file called the README.md. Here are a few other special files you can add to your repositories:

• CONTRIBUTING.md: The CONTRIBUTING.md is used to describe the process for contributing to the repository. A link to the CONTRIBUTING.md file is shown anytime someone creates a new issue or pull request.
• ISSUE_TEMPLATE.md: The ISSUE_TEMPLATE.md is another file you can use to pre-populate the body of an issue. For example, if you always need the same types of information for bug reports, include it in the issue template, and every new issue will be opened with your recommended starter text.

Using GitHub issues

Issues are used to discuss ideas, enhancements, tasks, and bugs. They make collaboration easier by:

• Providing everyone (even future team members) with the complete story in one place
• Allowing you to cross-link to other issues and pull requests ^📖
• Creating a single, comprehensive record of how and why you made certain decisions
• Allowing you to easily pull the right people and teams into a conversation with @-mentions
