 ##### Running on Cloud Dataflow
 
+Google Cloud Platform Dataflow workers need to be supplied with the tfrecorder
+package that you would like to run remotely.  To do so first download or build
+the package (a python wheel file) and then specify the path the the file when
+tfrecorder is called.
+
+Step 1: Download or create the wheel file.
+
+To download the wheel from pip:
+`pip download tfrecorder --no-deps`
+
+To build from source/git:
+`python setup.py sdist`
+
+Step 2:
+Specify the project, region, and path to the tfrecorder wheel for remote execution.
