A: Hello,

thank you for your questions here.

CNAME means you can have your documents on you sub domain instead of go.doclink.me
ref tutorial video here: https://www.youtube.com/watch?v=xvmXzyeJQH8

Once you point the CNAME to go.doclink.me ; we issue SSL for your subdomain.

Hope this helps.

Yes, it is for each doc.

Appreciate your early support.
Sumit :)
