+1. Create the `downstream-vX.Y.Z` branch based off main:
+```
+git fetch origin
+git switch --no-track -c downstream-vX.Y.Z origin/main
+git push downstream-vX.Y.Z
+```
+
+2. Branch `downstream-vX.Y.Z` so we can make the updates for the downstream code:
+```
+git checkout -b make-downstream-vX.Y.X (be sure to substitute the correct version for x.y.z, e.g. 2.0.0)
+make downstream
+git add/commit/push
+```
+3. Open PR against `downstream-vX.Y.Z` to merge the downstream code changes.
