*Short instruction:* answer the questions, follow the arrows, if you arrived at the yellow rectangle it's great, try the solution; if it doesn't work or if you have no arrow to follow next, read the red rectangle and follow this instruction to get more help.
If you have any questions or suggestions, please comment here. I'm not sure if I addressed all issues.
I didn't try to make it very pretty, I don't have time. If someone wants to make it more fancy, I can provide a .kra file.
