How to create template for burrowbeat template file?

Hi,

I have downloaded burrowbeat from https://github.com/Goomzee/burrowbeat and I built it. But it requires a template json file https://github.com/Goomzee/burrowbeat/blob/master/burrowbeat.template.json , which is empty. How should I configure that? Can somebody help me? When I run the beat, its showing error;

Exiting: error initializing publisher: Error loading template /data/setup/GA5/beats/burrowbeat/burrowbeat.template.json: EOF

Thanks.
