# TerraForgedAPI
### Dependency
```groovy
repositories {
maven {
url "https://io.terraforged.com/repository/maven/"
}
}
dependencies {
implementation "com.terraforged:TerraForgedAPI:1.15.2-0.0.1"
}
```
### Usage
TerraForged fires a number of setup events each time its chunk generator is created. These events expose certain
components of the generator allowing for world-gen content to be configured, modified, or added to.
See the `com.terraforged.api.TerraEvent` class for the available events.
All events are fired on the `FORGE` event bus.
