+# Twitch Plays Plotter
+
+The tale of the untested bit of javascript:
+
+the commands are right now
+- lb and anything you type after will be plotted as Text
+- init
+- pu
+- pd
+- up (move up by {distance})
+- down (move down by {distance})
+- right (move right by {distance})
+- left (move left by {distance})
+- rectangle (draw a rectangle with the size of {distance})
+- circle (draw a rectangle with the size of {distance})
+
+Also, there is the start of some state tracking and clamping to prevent the plotter from getting stuck. But again, untested.
