+Edit the [overworld.json file](https://github.com/TerraForged/Structure_Datapack/blob/main/data/minecraft/worldgen/noise_settings/overworld.json) to include the mod structures that you want to add with the desired separation settings.
+
+Add the edited datapack using the datapack selection screen in the Create World menus, or add to your `config/terraforged/datapacks` folder.
+
+### Notes on the settings:
+
+| Name | Valid_Value_Range | Unit | Description |
+| ---- | ---- | ---- | :---- |
+| salt | `0` - `2147483647` | None | Used as to seed the randomization of structure positions. |
+| spacing | `0` - `4096` | Chunks | Controls the size of the grid used to generate the structure. One structure will be placed randomly in each grid cell. |
+| separation | `0` < `spacing` | Chunks | Controls the minimum distance to maintain between the random structure positions. Low values produce more random distribution but may result in structures appearing closer together sometimes. |
