+# Obsidian LiveSync
+
+📝 Self-hosted Obsidian Sync mit CouchDB
+
+## Deploy in Komodo
+
+**Pfad:** `stacks/obsidian-livesync/`
+
+## Secrets
+
+- `OBSIDIAN_USER` - CouchDB Username (Default: `obsidian`)
+- `OBSIDIAN_PASSWORD` - CouchDB Password (openssl rand -base64 48)
+
+## Ports
+
+- `5984` - CouchDB API & Fauxton UI
+
+## Caddy
+
+```caddyfile
+obsidian.komodo.nocci.it {
+    reverse_proxy localhost:5984
+}
+```
+
+## Obsidian Plugin Setup
+
+1. **Plugin installieren:**
+   - In Obsidian: Settings → Community Plugins → Browse
+   - Suche: **"Self-hosted LiveSync"**
+   - Installieren & Aktivieren
+
+2. **Plugin konfigurieren:**
+   - Settings → Self-hosted LiveSync
+   - **CouchDB URI:** `https://obsidian.komodo.nocci.it`
+   - **Username:** Wie in `OBSIDIAN_USER` gesetzt
+   - **Password:** Wie in `OBSIDIAN_PASSWORD` gesetzt
+   - **Encrypt:** Optional (empfohlen für E2E-Verschlüsselung)
+
+3. **Vault synchronisieren:**
+   - Plugin führt initiales Setup durch
+   - Erstellt CouchDB-Datenbank automatisch
+   - Sync startet automatisch
+
+## Features
+
+- ✅ **Echtzeit-Sync** zwischen allen Geräten
+- ✅ **Konflikt-Auflösung** (auto-merge)
+- ✅ **E2E-Verschlüsselung** optional
+- ✅ **Settings/Plugins Sync** möglich
+- ✅ **Kostenlos** - kein $5/Monat Abo
+
+## Fauxton UI (CouchDB Dashboard)
+
+Zugriff auf die CouchDB Admin-Oberfläche:
+
+```
+http://localhost:5984/_utils
+```
+
+Login mit den gleichen Credentials.
+
+## Backup
+
+Daten liegen in Docker Volume `obsidian_data`.
+
+Backup-Pfad (typisch):
+```
+/var/lib/docker/volumes/obsidian-livesync_obsidian_data/_data
+```
+
+## Troubleshooting
+
+**Sync funktioniert nicht:**
+- Cloudflare Tunnel läuft?
+- Credentials korrekt?
+- Plugin auf "Sync enabled" gesetzt?
+
+**CouchDB nicht erreichbar:**
+```bash
+docker logs obsidian-livesync
+docker exec obsidian-livesync curl http://localhost:5984/_up
+```
