+# IrisPack
+The pack for iris
+
+# Flags
+Flags are for .ifl files
+
+## `raise <int>`
+Raises the schematic by X blocks upon placement such as `raise 3`
+
+## `sink <int>`
+Lowers the schematic by X blocks upon placement such as `sink 5`
+
+## `replace <find> <replace>,<replace>,<replace>...`
+Replaces one block type with one or multiple other block types
+
+```dockerfile
+# Replace ALL types of stone with STONE:3
+replace STONE STONE:3
+
+# Replace ONLY Stone (normal) with STONE:3
+replace STONE:0 STONE:3
+
+# Replace GRASS with random blocks
+replace GRASS DIRT,DIRT:1,DIRT:2
+```
+
+## `no snow`
+Do Not apply snow filter if this object will be placed in a snowy biome (if it already has snow)
+
+## `no lush`
+Do Not apply lush filter (vines) if this object will be placed in a lush biome (if it's already lush af)
+
+## `no rotation`
+Do Not create rotation variants of this object (always place in the direction it was saved)
+
+## `world chance <double>`
+Add additional rarity with world chance. 50% is `world chance 0.5` Use this with world radius
+
+## `world radius <int blocks>`
+Set a rarity window (radius) for this schematic. Checks rarity once per radius and either allows or denies placement depending on the check
+
+```dockerfile
+# This object will place inside of 256x256 regions 50% of the time
+world rarity 0.5
+world radius 128
+```
+
+## `gravity`
+Apply gravity to the base block of every column and pull the higher blocks down to the terrain height. Useful for land patches or walls. **NOT SUITABLE FOR OVERHANGS SUCH AS TREES**
+> Moderate Performance Impact
+
+## `maxslope <int>`
+
+Computes the base of the schematic (ignores overhangs) and tries to apply on the base (say the roots of a tree) If the base requires shifting higher than the slope value, placement fails. **This does not affect how the object looks, it's just a fail condition**
+> Moderate Performance Impact
+
+## `hydrophilic`
+
+Completley ignores the touching fluid check. This allows objects to be placed on top of water
+
+## `submerged`
+
+Treats water as air instead of the height of the terrain. Allows placement UNDER water on the sea-bed surface
