+This must be defined by player. Each player number should be listed with the appropriate section. Each section is a list of placement rules. Each placement rule has a specific type.
+
+Supported Types: PlacementGroup, NotPlacmentGroup
+
+#### PlacementGroup
+
+You may define an item, and a list of locations. The locations may be weighted if desired. The item will be placed at one of the listed locations - this currently ignores logic. The item will be placed there. The special location 'Random' indicates that the item should be placed randomly, without any other consideration. This may be repeated for placement of multiple items like multiple bows or swords.
+
+#### NotPlacementGroup
+
+You may define an item and a list of locations that an item should not be placed at. This will apply to all items of that type. The logic is considered for this. If it is otherwise impossible, the item will be considered for the listed locations. This is important for small key layouts mostly, but it will try other locations first.

+This must be defined by player. You may have prize packs, tree pulls, crab drops, stun prizes, and the fish prize defined using the following keys:

+     - Random

+    Crab Normal: Rupees (20)
+    Crab Special: Small Magic
+    Stun Prize: Bombs (8)
+    Fish: Big Magic
+```
+
+Prize packs expect a list of eight items each (anything not specified will be whatever randomization would have normally occurred). The special drops expect a single item. Packs 1 through 7 are supported. Prize pack 0 is not customizable.
