Start the program, then choose to either scramble the cube with the bottom left button, or try out some algorithms. If you ever get stuck and want to start over, just click the solve button.
The buttons are in English and Spanish, because some of my friends speak Spanish. It is a bit buggy, and also to solve it you have to end the solve with green on the front, red on the right, and white on the top. Thanks to @HexarHunter for helping me
