 Хост: `board.kzntsv.site` за traefik на VDS. Обновление: cron-тик ~5 мин, перегенерация статической HTML.
 
-Design: see `.wiki/concepts/` (after promote from `.workshop/.brainstorm/board-viewer.md`).

 ## Quick start
 
-<!-- TBD после первого impl-prototype -->
+```bash
+npm install
+npm test                                # 43 tests
+npm run typecheck
+
+# Local build (writes ./dist):
+node --experimental-strip-types src/cli.ts <path-to-auth.toml>
+# auth.toml needs: gitea_url, gitea_token, board_viewer_repos = ["owner/repo", ...]
+# See deploy/auth.toml.example for the full shape.
+
+# Then open dist/index.html via any static server, e.g.
+( cd dist && python -m http.server 8765 ) &
+# → http://localhost:8765/
+```
+
+## Deploy
+
+See `deploy/README.md` — Docker-compose stack on VDS, Traefik route + basic-auth.
+
+## Architecture
+
+```
+src/parser.ts   STATUS.md (markdown)            → StatusBlock[]   (pure)
+src/gitea.ts    Gitea HTTP API (DI'd fetch)     → file content + last commit ISO + raw URL
+src/reader.ts   readBoard(client, repos)        → TaskRecord[]    (orchestrator)
+src/render.ts   renderBoard(records, opts)      → HTML string     (pure)
+src/cli.ts      load config → reader → render   → dist/index.html + dist/static/
+static/         CSS + ESM JS (filter, drawer, toggle-grouping)
