-Formless 3 is not yet in the package sets. You can add it manually to your package set with the addition below. This library also requires `variant >= 7.1.0`, which you may need to add to your pacakge set as well.
+Formless 3 is available in package sets beginning with `psc-0.14.7-20220303`. If you are using an older package set, then you should add an override to your `packages.dhall` file as in the example below. Older package sets do not include `variant >=7.1.0` either, so you will need to override that also.
