+## Setup
+
+```bash
+# 1) Datenbanken + MinIO starten
+docker compose up -d
+
+# 2) Umgebungsvariablen
+cp .env.example .env
+
+# 3) Workspace kompilieren + Tests
+cargo test --workspace
+cargo check --workspace
+
+# 4) Tauri-Frontend (Vite dev)
+cd crates/tauri-app
+npm install
+npm run dev
+# → http://127.0.0.1:1420
+
+# 5) PDS / AppView (eigene Terminals)
+cargo run -p pds-server
+cargo run -p appview
+```
+
+## Status
+
+| Phase | Stand |
+|-------|-------|
+| 0  Foundation, Workspace, Migrations, Lexicon, Crypto | ✅ done |
+| 1  Identity (PLC-Ops vollständig signieren) | ⏳ TODO (JWT-PEM fehlt) |
+| 2  MST + Repo (Spec-konforme CBOR-Encoding) | ⏳ Skelett steht |
+| 3  PDS-Server (com.atproto.* XRPC) | ⏳ Skelett, nur Healthz |
+| 4  AppView-Foundation (Jetstream-Index) | ⏳ Skelett |
+| 5  AppView-REST-API | ⏳ Stubs |
+| 6  Tauri-UI-Logik an Backend koppeln | ⏳ Stubs |

+Der eine ignored Test (`jwt::issue_and_verify`) braucht noch einen ASN.1-SEC1-PEM-Encoder — geplant für Phase 1.

+## Design
+
+Orange Akzent, IBM Plex Mono, schwarzer Hintergrund mit 3%-Grid, Terminal-Fenster-Component mit blinkendem Cursor. Tokens sind 1:1 von `maarcade-shell/landing/assets/css/tokens.css` abgeleitet, plus zwei neue Repos-Tokens (`--cid-fg`, `--rev-fg`).
