 ## Developer Notes:
+* games_path and mods_path should not be stored in minetestmeta.yml, since otherwise the values may deviate from the parent directories.
+To avoid this problem, instead derive the paths from the parent paths using your favorite language such as in the following examples:
+	games_path = os.path.join(minetestinfo.get_var("shared_minetest_path"), "games")
+	#KEEP IN MIND: gameid in world.mt is the name of the game FOLDER (NOT the name variable in the folder's game.conf)
+	mods_path = os.path.join(minetestinfo.get_var("game_path"), "mods")
+* Keep in mind that gameid (in game.conf in a subgame folder, and world.mt in a world folder) is NOT case-sensitive: for example, minetest_game has the gameid 'Minetest' (first letter capitalized) but the worlds generated by Minetest client have the gameid 'minetest' (lowercase) in their world.mt
 * the map update function is only able to detect new chunks, and only checks edge chunks if player is present in one
 * The following are saved to chunkymap.yml if not already set:
 www_minetest_path (such as /var/www/html/minetest)
