Help for "obtain a trusted certificate" doesn't help

Question

In particular the following text in the Help Center:
Select your server in the sidebar, and then click Settings.
Click the Edit button at the right of SSL Certificate.
From the Action pop-up menu (looks like a gear), choose Manage Certificates.
In the Manage Certificates pane, select the self-signed certificate you want to use to generate the CSR.
From the Action pop-up menu (looks like a gear), choose Generate Certificate Signing Request (CSR).
Save the CSR file.
I'm running the Server app.  (This is the right thing, yes?)  2.2.1  First step works fine.  But there doesn't seem to be an "Edit button" at the right of SSL Certificate.  Or an SSL Certificate.  But I seem to recall MAKING a certificate, yes... I see it now.  Under the Certificates selection in the sidebar.  But no "manage certificates" or some such.  But I THOUGHT I saw such a thing... somewhere...

Ah...   Thanks for both points.  I was specifically looking for a "request trusted certificate" path, which the Keychain tool didn't (explicitly) show me, though it DID show a whole slew of certificates that I never knew I had (nor understand exactly what they are about, but, "I am but an egg" on these things.)
Back on the Server app, it is the + button on the certificates field, so correct documentation might be something along the lines of...
Select "Certificates" under the "Server" group on the sidebar.
Click the "+" at the bottom of the server list.
Select "Get a Trusted Certificate" from the pop-up menu.
... (I'll know better when I actually perform the steps)
I hope this will advance the cause.
