steps to put a skuid app in the app store

There’s a good thread on this over at this link - https://community.skuid.com/t/isv-app-test-drive-trialforce-etc

Basically the steps should be: 
- upload your managed package to the appExchange,
- successfully pass the security review
- spin up a Trialforce org from your environment hub
- install Skuid into that TF org
- install your app into that TF org
- create sample data in your app in the TF org

Then when users install from the AppExchange they should get an exact copy of the TF org.

Just one question - how is it going to be a free app? users will at least have to pay for the Skuid licences won’t they?
