-a. Drag and drop binaries into the web form.
-
-There is a box labeled "Attach binaries by dropping them here or
-selecting them".  Drag dnscontrol-Darwin, dnscontrol-Linux, and
-dnscontrol.exe onto that box (one at a time or all at once). This
-will upload the binaries.
+Make sure the "This is a pre-release" checkbox is UNchecked. Then click "Publish Release".
 
-b. Submit the release.
+b. Wait for workflow to complete 
 
-Make sure the "This is a pre-release" checkbox is UNchecked. Then click "Publish Release".
+There's a GitHub Actions [workflow](https://github.com/StackExchange/dnscontrol/actions?query=workflow%3Arelease) which automatically builds and attaches
+all 3 binaries to the release. Refresh the page after a few minutes and you'll
+see dnscontrol-Darwin, dnscontrol-Linux, and dnscontrol.exe attached as assets.
