+Decoration types
+-------------------
+The varying types of decorations that can be placed.
+The default value is simple, and is currently the only type supported.
+
+- simple
+ Creates a 1xHx1 column of a specified node (or a random node from a list, if a decoration
+ list is specified). Can specify a certain node it must spawn next to, such as water or lava,
+ for example. Can also generate a decoration of random height between a specified lower and
+ upper bound. This type of decoration is intended for placement of grass, flowers, cacti,
+ papyrus, and so on.
