The documentation lists non-existent "unit" command

Problem

I am a new user evaluating ketch. The documentation lists non-existent "unit" command

https://learn.theketch.io/docs/unit-management

Questions

1. How does one scale a deployment?
2. Is there a feature to generate a HPA?

Example

$ ketch app list
NAME             FRAMEWORK    STATE        ADDRESSES                                                                                         BUILDER    DESCRIPTION
bulletinboard    dev          3 running    http://bulletinboard.X.X.X.X.shipa.cloud https://bulletinboard.xxx.duckdns.org    

$ ketch unit add 5 --app bulletinboard
Error: unknown command "unit" for "ketch"
Run 'ketch --help' for usage.
2023/01/03 18:35:12 execution failed "unknown command \"unit\" for \"ketch\""
