I'm working on the prework for the Lightning Experience Rollout Specialist badge.  I created a new playground and installed the unmanged package.  I'm now stuck on these two steps:

1. From Setup in either Salesforce Classic or Lightning Experience: Create a user named John Wiseman and assign him to the Salesforce user license and the Custom: Sales Profile profile.
2. Create a second user named Paloma Espinoza and assign her to the Salesforce Platform user license and the Standard Platform User profile.

I have not "Salesforce" user license and if I choose "Salesforce Platform" license it tells me there are No Salesforce CRM Content User Licenses Available. 


Any thoughts?
