Blox owners are requesting a video walk through to further ease the onboarding and setup process.

Two videos should be created:

1. One for the RK1 (#158)
2. One for CM4 (#159)

Videos should go over:

• How to tell it apart
• How to update firmware manually
• How to add storage
• How to set it up in the app
