+            Excalidraw is deployed and available as $$cap_appname. 
+
+            Before starting using Excalidraw, you'll need to
+
+            1) Enable HTTPS for $$cap_appname-room, $$cap_appname-storage and $$cap_appname apps.
+
+            2) Force HTTPS by redirecting all HTTP traffic to HTTPS for $$cap_appname-room, $$cap_appname-storage and $$cap_appname apps.
+
+            3) Enable Websocket in $$cap_appname-room, $$cap_appname-storage and $$cap_appname apps.
+
+
+            IMPORTANT: It will take up to 1 minutes for Excalidraw to be ready. Before that, you might see 502 error page.
