Thank you for noticing this :) I think the content from both pages could be consolidated and improved. That said I think the platform operators page should be more detailed and should answer (or contain links to) questions such as:

• How do I find out what is contained within a builder?
• How do I customize a builder?
• How do I create my own builder?

Whereas the app developers page should should answer (or contain links to) questions such as:

• How do I choose a builder from the available providers?
• How do I set a builder as a default?
• How do I receive updates to a builder?

The app developers page could link to the platform operators page as a way of going deeper. But, maybe there is a better way to do it that we haven't thought of :)

This is helpful. Yep we can make it different for each persona so that they can understand the same concept with a different point of view
