A Github repository is basically a folder designed to store files. It is also available online for anyone to download, access, and contribute to the files/code within the folder.

Good news for those with active GitHub profiles: you can now add files to your repos by dragging and dropping them into the browser. Once a file is uploaded, you can add it to an existing branch ...

GitHub will then keep track of the changes you made, creating different versions of files so you can revert back to old ones if you want (or just keep track of those changes for other reasons).
