The attached file is the YAML code that you guys provided me in an earlier ticket I had opened regarding setting up this SSL Cert to use with "Let's Encrypt". I am not that familiar with where to plug in my domain name, the OAuth2 Client key, and the Secret key.

Could you please look over my attached file, I highlighted the lines that I think I need to plug-in the info like domain name etc?

If my markups are wrong please direct me to the lines within the code to enter the specific info. I would be very grateful for your assistance.
