We don't need instructions to do it manually.

However, since we've not used this bit of automation in a fully organic
fashion, we'll leave a note to verify that it's worked.

Changes:
 * Add step #s.
 * In `4.6`, include the "Sanity Check". This is already addressed in `4.7`, but they need to do it at different times (`rc` vs `final`).

Use fewer words.
