--- This program digs a mining stairs with a five levels down per filght of stairs
+-- This program digs a mining stairway with a flight of stairs five steps deep and two wide
--- Pastebin code = "TaFFELNp"; Pastebin name is "MDC_Stairs_Cut2"
+-- Pastebin code = "31Vzy3bj"; Pastebin name is "MDC_Stairs_Cut3"
 
--- This program assumes that you place the turtle down on the forward end of the upper pad (a 2 stone x 2 stone)
+-- Place the turtle down on the right-forward end of the upper pad (a 2 stone x 2 stone)
--- Place coal into Turtle slot #1 to assure adequate fueling
+-- Place coal into Turtle slot #14 to assure adequate fueling
--- Place stone into Turtle slot #2 and #3 to assure adequate placement resources
+-- Place stone into Turtle slot #15 and #16 to assure adequate placement resources
 -- This program begins by asking you to indicate whether you want to cut an upper hall (H response) or stairs (S response)
