What are you trying to work out?
Keep the learning path narrow. Use the fit guide to decide whether Capell suits the project, or the content-model examples to identify repeatable page structure. The platform owns product boundaries, and the documentation owns implementation steps.
Bring one question at a time. Each guide below ends in a decision you can act on, not a reading list.
Keep going
Take a settled decision to the detail
The learning centre stops at the decision. Product boundaries belong to the platform overview, and installation and API steps belong to the documentation.
Both guides above end where implementation begins. Take a settled content model to the documentation for the field, blueprint, and route work, or to the platform overview when the open question is still what Capell does and does not own.
