## Quick Start

```java
// Builder tools are enabled in creative mode
// Players can use selection and editing commands

// Programmatic access to builder tools data via ECS components
import com.hypixel.hytale.builtin.buildertools.BuilderToolsPlugin;
import com.hypixel.hytale.builtin.buildertools.BuilderToolsUserData;
import com.hypixel.hytale.component.CommandBuffer;
import com.hypixel.hytale.component.Ref;

// Get the component type
BuilderToolsPlugin builderTools = BuilderToolsPlugin.get();
ComponentType<EntityStore, BuilderToolsUserData> userDataType = builderTools.getUserDataComponentType();

// Access user data via command buffer
BuilderToolsUserData userData = commandBuffer.getComponent(playerRef, userDataType);
```
