--- A door is basically just 2 panes (using `lzr_panes`),
--- with a top segment and a bottom one. Panes are useful because
--- they are laser-compatible.
+There are two types of doors: Locked doors play a sound when
+interacting with them and exit doors that allow the player
+to exit the level.
 
--- Door segments are completely standalone, it is the reponsibility
--- of the map author to construct correct doors.
