5.0 - Couldn't fine nginx.conf file inside downloaded ng

Hi,

I Couldn't find the nginx.conf file inside conf folder in order to configure nginx as mentioned. (https://documentation.progress.com/output/rb/doc/5.0/index.html#page/rb%2Fconfiguring-nginx.html%23)

Other mentioned configuration files such rb-upstreams.conf , rb-locations.conf and proxy.conf also not available in the same folder. 

I downloaded the nginx.zip file from https://www.progress.com/trial-rollbase-private-cloud 

Do we have to create these files ourselves?

Regards,
Ithrees
