 * hiddenTiles: Exactly like hiddenWalls, except for tiles.
 * walls: A wall tile is any tile that causes the player to collide. It doesn't have to be a wall or even a tree. It could be a regular ground tile too. Just remember that placing a tile in this layer would cause the player to not be able to walk there.
 * doodads: This layer does not cause collisions and is rendered brighter than the tile layer.
-* tiles: Regular tiles that don't collide and are rendered fairly dim. Use this for all ground tiles like carpets, grass, dirt and water.

+##### The Zone File
+
+An empty zone file looks like this:
+
+```
+module.exports = {
+	resources: {
+
+	},
+	objects: {
+
+	},
+	mobs: {
+	
+	}
+};
+```
+
+The different sections are:
+* resources: Used for herbs that should spawn in the zone.
+* mobs: Used for enemy mobs and NPCs.
+* objects: This is used for everything else. For instance: portals (to other zones), doors, light sources, dialogue triggers, or anything that emits particles.
+
+###### Resources
+
+The resources section is fairly straight-forward. Here's an example:
+
+```
+resources: {
+	Moonbell: {
+		type: 'herb',
+		max: 5
+	}
+}
+```
+
+The key (Moonbell) tells the game which type of herb should spawn. Options are:
+* Moonbell
+* Skyblossom
+* Emberleaf
+
+The `max` variable defines how many nodes can be active at the same time.
+
+###### Mobs
+
+Besides definitions for specific mobs, any of these values can be defined for mobs in a `default` key:
+
+```
+mobs: {
+	default: {
+		level: 1,
+		faction: 'gaekatla',
+		walkDistance: 1,
+
+		spells: [{
+			type: 'melee',
+			statMult: 0.1356
+		}],
+
+		regular: {
+			hpMult: 1,
+			dmgMult: 1,
+
+			drops: {
+				chance: 35,
+				rolls: 1
+			}
+		},
+
+		rare: {
+			count: 1,
+			chance: 1,
+
+			hpMult: 1,
+			dmgMult: 1,
+
+			drops: {
+				chance: 100,
+				rolls: 1,
+				magicFind: 75
+			}
+		},
+
+		champion: {
+			hpMult: 1,
+			dmgMult: 1,
+
+			drops: {
+				chance: 100,
+				rolls: 2,
+				magicFind: 115
+			}
+		}
+	}
+}
+```
+
+Over and above that, you can also define a section that's specific to your mob. As an example, let's say you've got a mob named `Brutus`. His section could look like this:
+
+```
+mobs: {
+	brutus: {
+		level: 5,
+		walkDistance: 0
+	}
+}
+```
+
+Note that the name has to be lower case here. If his name was `Brutus the Defender` you would use `'brutus the defender'` as his key. From here you can customize Brutus further by allowing him to be a rare mob 20% of the time and giving him 3 chances to drop an item with each roll being a 50/50:
+
+```
+mobs: {
+	brutus: {
+		level: 5,
+		walkDistance: 0,
+
+		regular: {
+			drops: {
+				rolls: 3,
+				chance: 50
+			}
+		},
+
+		rare: {
+			count: 1,
+			chance: 20
+		}
+	}
+}
+```
+
+Remember, drops are defined for regular, rare and champion. Just because we gave Brutus 3 drops, doesn't mean he'll drop 3 items if he's rare, we need to define that separately. Alternatively, we can set it globally for the map too.
