+// *** CONSTRUCTION NOTES ***
+// If using this script, put the annabuncheskOS-launchpad.cfg file from the patches/ directory into your GameData/
+//   directory. This will ensure the launchpad has a high enough fuel flow rate for the spool-up sequence.
+// If your lower stage uses engine plates, be sure to attach the launch pad to one of the *engine* bottom nodes,
+//   not the Engine Plate's bottom node. Otherwise fuel delivery won't work.
+//
 // *** TAGGING REQUIREMENTS ***
 // The launchpad object should have the "launchpad" tag.
 // The ship's main CPU (the one with launch functionality" should be tagged "shipcpu".
 // Fuel tanks with the "nofuel" tag will have *all* resources temporarily disabled during the pre-launch
-// sequence. The main ship computer must re-enable them after staging. NoFuelResources() in lib/systems is ideal
-// for this.
