+### Bundle Types
 
 LLRT publishes several binaries with different sets of bundled SDKs:
 
-- `LlrtBundleType.FULL_SDK`: Includes all AWS SDKs
-- `LlrtBundleType.NO_SDK`: No AWS SDKs included
-- `LlrtBundleType.STANDARD`: Standard bundle (default)
+- `LlrtBinaryType.FULL_SDK`: Includes all AWS SDKs
+- `LlrtBinaryType.NO_SDK`: No AWS SDKs included
+- `LlrtBinaryType.STANDARD`: Standard bundle (default)
 
 You can specify the bundle type when creating a new LlrtFunction:
 
 ```ts
 const handler = new LlrtFunction(this, 'Handler', {
     entry: 'lambda/index.ts',
-    bundleType: LlrtBundleType.FULL_SDK,
+    binaryType: LlrtBinaryType.FULL_SDK,
 });
 ```
