Regarding following the documentation, I would suggest that either at the end of a documentation section or at the beginning of the next section to have a checklist of items that should be in place and showing as active to proceed to the next section,
Example pages of what various devices should look like after detection would be helpful for users to identify possible problems.
Longer range I would suggest an audit tool that could be run which would flag things that are likely incomplete or incorrect in the configuration such as the "UnknownATV" I encountered in AndroidTV discovered devices.
