# Biomes

In Ouranos, you can change the biomes that will appear in your world. To do that, modify the **biomes** value into the desired world configuration file. To add a biome add a line with these values : 

```
- Ouranos:<biome_name> # For Ouranos biomes
- Custom:<biome_name> # If it's a custom biome
```
