+# Room Setup
+
+Two ways to create a room: CLI wizard or web wizard.
+
+```bash
+# CLI wizard
+python -m init.cli myroom
+
+# Web wizard (opens browser on :9000)
+python -m init.web
+
+# Clone from existing room
+python -m init.cli myroom --from sample
+```
+
+## Layers
+
+Each layer is optional beyond layer 0.
+
+| Layer | What | Files |
+|-------|------|-------|
+| 0 | Config + Data | `config.json`, `data/*.json` |
+| 1 | Docker | `soleprint/docker-compose.yml`, `.env` |
+| 2 | Managed App | `docker-compose.yml`, Dockerfiles, `.env` |
+| 3 | Link | `link/main.py`, `adapters/`, Dockerfile |
+| 4 | Scripts | `ctrl/start.sh`, `stop.sh`, `status.sh`, `logs.sh` |
+| 5 | Systems | tester environments, test scaffolds |
+| 6 | Nginx | `nginx/local.conf`, `docker-compose.nginx.yml` |
+
+![Room Layers](../graphs/room_layers.svg)
+
+The wizard adds layers incrementally. Layer 0 is always created. Each subsequent layer builds on the previous ones but none are required.
+
+## Build
+
+After the wizard finishes, build the room:
+
+```bash
+python build.py --cfg myroom
+```
+
+Output goes to `gen/myroom/`. The build merges room-specific configs from `cfg/myroom/` into the base framework.
