->As in the image above, once you have copied there may be a pop-up with a suggested 'proj/'. If you click on this, the Tcl Console will automatically flip the slashes in the address from back slashed ( / ) to forward slashes ( \ ). This is a bit mundane but is important since the console will not recognize the address with the backslashes. If it does not automatically correct them, just go in manually and replace each back slash with a forward slash. 
-> 
->Again, as illustrated in the images, type in "source ./" and select the auto-fill suggestion 'create_project.tcl' and hit enter. Your project will build and the window will look similar to the one pictured below.

 To run all the features of this demo, all you will need is your programmed Basys3. The abacus can preform 4 arithmatic functions on two 8-bit numbers. Switches 15-8 represent input A. Switches 7-0 represent input B. The abacus works by setting the slide switches to your desired operands and then selecting an operation with the buttons. The result will be displayed on the 7 segment display. On startup, the display will read 0. To run all the features of this demo, all you will need is your programmed Basys3.
