+## Caddy Configuration
+
+The Caddy reverse proxy on Mini PC 2 must have a handle block for each route
+prefix the client needs to reach. Current required blocks:
+
+```
+handle /chat* {
+    reverse_proxy localhost:4000
+}
+handle /sessions* {
+    reverse_proxy localhost:4000
+}
+handle /models* {
+    reverse_proxy localhost:4000
+}
+handle /projects* {
+    reverse_proxy localhost:4000
+}
+```
+
+When adding new top-level routes to the orchestration service, add a matching
+block here and reload Caddy: `caddy reload --config /path/to/Caddyfile`
