+## Chat Client Deployment
+
+The chat client is a React + Vite app build to static files and served by Caddy on Mini PC 2 (Infrastructure node).  It does not run as a Node process
+```bash
+# On dev machine or Mini PC 2 after git pull
+cd ~/nexusAI/packages/chat-client
+npm run build
+# Output lands in packages/chat-client/dist/
+# Caddy serves this directory directly via volume mount
+```
+Caddy config (`/opt/docker/caddy/Caddyfile`):
+```caddy
+nexus.jellystorm.com {
+    import authelia
+
+    handle /chat* {
+        reverse_proxy 192.168.0.205:4000
+    }
+
+    handle /sessions* {
+        reverse_proxy 192.168.0.205:4000
+    }
+
+    handle {
+        root * /srv/nexusai
+        try_files {path} /index.html
+        file_server
+    }
+}
+```
+
+The Caddy container mounts the dist directory via Docker volume:
+```yaml
+- /home/storme/nexusAI/packages/chat-client/dist:/srv/nexusai
+```
+
+> After adding or changing volume mounts, a full `docker compose down caddy && docker compose up -d caddy`
+> is required. Caddyfile-only changes only need `docker compose restart caddy`.
+
+
+
 ## Environment Files
 
 Each node needs a `.env` file in the relevant service package directory.
