Configure SSL for readyapi virtual services

I have ssl certificate (.cer) file and ssl certificate key (.key) for the virtserver computer. Could you please let me know how to enable SSL in virt-server.yml file.

Also should I configure something in "Ready API Preferences" ==> "SSL Preferences" ?

Please note: I don't find the procedure in this URL: Use Custom SSL Certificates for VirtServer | VirtServer Documentation (smartbear.com)

Could anyone please help me with steps.?
