Reading the Tensorflow text summarization documentation setup : https://github.com/tensorflow/models/tree/master/textsum it states clone the code to your workspace and create empty WORKSPACE file.
I've created a new folder and cloned https://github.com/tensorflow/tensorflow.git to this folder , is that what is meant by 'clone the code to your workspace' ? What is an empty workspace file ? Is it an empty file named 'WORKSPACE' ?
