Hey fellow Munchkins,
I was tired of explaining the rules to new players over and over again and I also didn't like the plain flowcharts you can find everywhere, so I came up with this one:

It does not fit on one page, but since it is optimised for mobile screens anyway, there is no need to print it out.
If you have any suggestions for improvement, please feel free to comment! I could also send you the original Photoshop file, if you want to adapt it yourself or translate it.
