--- This program digs a mining stairway with a flight of stairs five steps deep and two wide
+-- This program creates a tunnel liner to facilitate mining via 5 x 5 tunnels
--- Pastebin code = "31Vzy3bj"; Pastebin name is "MDC_Stairs_Cut3"

--- Place the turtle down on the right-forward end of the upper pad (a 2 stone x 2 stone)
+-- Place the turtle down on the right-forward end of the tunnel cut.
 -- Place coal into Turtle slot #14 to assure adequate fueling
 -- 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)
+-- This program begins by asking you how many two-block sections you want to cut
