Pick a colour. It shows you the options in the project. Pick a pen size from 1 - 10. 1 is small, 10 is big. Draw things on the screen by holding down on the mouse and moving the mouse around . You can also just click on different places on the screen to connect them with lines. Click on Eraser to clear the screen.
If you notice a glitch in the project, comment what it is. I won't be offended. There still are some problems with it, but it works okay if you aren't trying to do a portrait or some really good drawing.
