I allowed my macOs to get old. Now I have to update it. Need to upgrade from v10.12.6 “Sierra” to v10.13.6 “High Sierra”. On0line instructions are always inconsistent with what I see on my screen. I download SecUpd2020-005HighSierra.dmg to ~/Downloads. Can I update from that? What is best?

No, that's a security update. Before you can use that you will need to have High Sierra installed.
Search the App Store.
Thanks for both responses. And yes, the link was a big help. I had not been able to find it with a search.
