In the early days of personal computers you would purchase software on a 5 1/4 inch floppy disk as shown in this photo.
Typically in the root directory of the floppy you would find a text file named README.TXT or README.1ST that would give you the setup instructions of the program on the floppy disk.
The instructions for use of the Geekhistory website are to open your mind and explore who invented the internet, the history of computers, and the origins of all things geek.
