*   what is git?
    *   a popular distributed version control system

    *   invented by Linus Torvalds

    *   distributed? means you run it locally -- you keep
        a local copy -- and you can also keep copies
	elsewhere - DISTRIBUTE copies, distributed
	across multiple computers, across networks, etc.

    *   version control? you can check in copies of files
        as they are developed, and have the option of
	checking previous versions out again later;

*   what is GitHub?
    *   a web-based HOSTING service for projects (usually
        software development projects) that use git

    *   provides free public repositories, or repos --
