+#SPREED
+"Spread" + "Speed"
+Spreed started as a standalone WebRTC project, originally developed by the German company struktur AG.
+Struktur AG was later acquired by Nextcloud GmbH, and Spreed became tightly integrated with Nextcloud Talk.
+| Feature                    | Role of Spreed                                   |
+| -------------------------- | ------------------------------------------------ |
+| **Video & voice calls**    | Handles WebRTC signaling for 1:1 and group calls |
+| **Text chat**              | Powers chat rooms, messages, mentions, etc.      |
+| **Screensharing**          | Facilitates screen sharing over WebRTC           |
+| **TURN/STUN support**      | Helps users connect through firewalls/NATs       |
+| **Signaling server**       | Coordinates call setup between users             |
+| **Multiparty conferences** | Manages group call state and media routing       |
+The High-performance backend developed by our Partner Struktur AG available in their 
+GitHub organisation. 
+The High-performance backend itself consists of multiple modules, the most important ones 
+being a: 
+- signaling server and a 
+- WebRTC media gateway.
+
+Nextcloud Talk comes as an app within Nextcloud, but it needs 
+- Spreed (the WebRTC backend) and a 
+- TURN server for video and audio calls. The best practice is to set up Coturn for this.
+
+#TURN server: 
+This acts as a fallback for peer-to-peer connections if direct connection fails.
+A TURN server is used to proxy the traffic from participants behind a firewall. 
+If individual participants cannot connect to others a TURN server is most likely required
+Voor Matrix en Nextcloud gebruiken we coturn. coturn draait in cluster LattePanda en is door traefik exposed op poorten:
+
+ - name: turn-udp
+containerPort: 3478
+protocol: UDP
+ - name: turn-tcp
+containerPort: 3478
+protocol: TCP
+ - name: turns-tcp
+containerPort: 5349
+protocol: TCP
+
+#STUN server: 
+This is used to discover the public IP address of a client when it's behind a NAT (e.g., router).
