+# Keycloak Setup für r/place
+
+## Keycloak Installation
+
+### Docker (Empfohlen)
+```bash
+docker run -d \
+  --name keycloak \
+  -p 8080:8080 \
+  -e KEYCLOAK_ADMIN=admin \
+  -e KEYCLOAK_ADMIN_PASSWORD=admin \
+  quay.io/keycloak/keycloak:latest \
+  start-dev
+```
+
+### Standalone Installation
+1. Lade Keycloak von https://www.keycloak.org/downloads herunter
+2. Entpacke das Archiv
+3. Starte Keycloak: `bin/kc.sh start-dev`
+
+## Konfiguration
+
+### 1. Admin Console öffnen
+Gehe zu http://localhost:8080/admin und melde dich mit admin/admin an.
+
+### 2. Realm erstellen
+1. Klicke auf "Create Realm"
+2. Name: `rplace`
+3. Klicke "Create"
+
+### 3. Client erstellen
+1. Gehe zu "Clients" → "Create client"
+2. Client ID: `rplace-client`
+3. Client type: `OpenID Connect`
+4. Klicke "Next"
+5. Client authentication: `OFF` (Public client)
+6. Standard flow: `ON`
+7. Direct access grants: `ON`
+8. Klicke "Save"
+
+### 4. Client Settings
+1. Gehe zu deinem Client `rplace-client`
+2. Settings Tab:
+   - Valid redirect URIs: `http://localhost:5000/*`
+   - Valid post logout redirect URIs: `http://localhost:5000/*`
+   - Web origins: `http://localhost:5000`
+3. Klicke "Save"
+
+### 5. Test User erstellen
+1. Gehe zu "Users" → "Add user"
+2. Username: `testuser`
+3. Klicke "Create"
+4. Gehe zum "Credentials" Tab
+5. Setze ein Passwort und deaktiviere "Temporary"
+
+## r/place Konfiguration
+
+Bearbeite `config.cfg`:
+```ini
+ENABLE_KEYCLOAK=true
+KEYCLOAK_REALM=rplace
+KEYCLOAK_AUTH_URL=http://localhost:8080
+KEYCLOAK_CLIENT_ID=rplace-client
+```
+
+## Erweiterte Konfiguration
+
+### HTTPS (Produktion)
+Für Produktionsumgebungen:
+```ini
+KEYCLOAK_AUTH_URL=https://dein-keycloak-server.de
+```
+
+### Benutzer-Attribute
+Du kannst zusätzliche Benutzerattribute in Keycloak konfigurieren:
+1. Gehe zu "Client scopes"
+2. Bearbeite "profile" scope
+3. Füge Mappers für zusätzliche Attribute hinzu
+
+### Sicherheit
+- Ändere Admin-Passwort
+- Konfiguriere SSL/TLS
+- Setze starke Passwort-Richtlinien
+- Aktiviere Brute-Force-Schutz
+
+## Fehlerbehebung
+
+### CORS-Probleme
+Stelle sicher, dass die Web origins korrekt konfiguriert sind.
+
+### Token-Probleme
+Überprüfe die Client-Konfiguration und Redirect-URIs.
+
+### Verbindungsprobleme
+Stelle sicher, dass Keycloak erreichbar ist und die URLs korrekt sind.
