Valve has published a “Getting Started” page through its official “Steam Hardware” curator, featuring setup videos for its hardware trio: Steam Frame, Steam Machine, and Steam Controller.
Most of the videos focus on the VR headset Steam Frame, which gets eight short clips of its own:
Unboxing & Turning On Fit & Comfort Adjusting the IPD Signing in to Steam Streaming & Using the Wireless Adapter Ergonomic Accessories Kit Installing the Controller Hand Straps Installing the Top Strap & Light Blocker
Steam Machine and Steam Controller each get one “Overview & Quick Start Guide” video.
