 ### File Processing
 
 This sample has two executables. Execute each command in a separate terminal window. The first command
 runs the worker that hosts the workflow and activities implementation. To demonstrate that activities
 execute together, we recommend that you run more than one instance of this worker.
 
-    ./gradlew -q execute -PmainClass=com.uber.cadence.samples.fileprocessing.FileProcessingWorker
+    ./gradlew -q execute -PmainClass=io.temporal.samples.fileprocessing.FileProcessingWorker
 
 The second command starts workflows. Each invocation starts a new workflow execution.
