The
Guide.
Design thinking, behind every decision.
The full Guide lives inside DOS Mode — a two-column documentation window with interactive demos, annotated diagrams, and section-by-section breakdowns of every system on this site.
It covers the terminal, the window system, slimes, Goop, themes, the mobile experience, hidden features, and the production stack — including how AI tools, Figma, Claude Code CLI, and Git fit together into a real product development lifecycle.
What's inside
- Introduction — what D.O.S is and why it was built this way
- Terminal & Commands — the command system, keyword fallback, and design philosophy
- Window System — floating windows, traffic-light controls, cascade positioning, and glass rim
- Slimes — physics, merging mechanics, color system, and resident window tinting
- Goop — character design, behavioral state machine, speech bubbles, and voice
- Themes & Palettes — seven palettes, live transitions, CSS architecture, and font system
- Mobile Experience — how the OS metaphor adapts to small screens
- Secrets — hidden commands, easter eggs, and the hint system
- How It’s Built — the full production stack, AI governance model, and the human+AI symbiosis
