 # Multi-Tenant Optimized Docker Compose
-# Supports running multiple isolated app instances per subdomain
+# Supports running multiple isolated app instances with direct Docker host port binding
 # Each instance: ~50MB base + 20-30MB per 20 users
 # 
 # Usage:
 #   docker-compose -f docker-compose-multitenant.yml up -d
 #
-# Scale example: To support 10 tenants with 20 users each:
-#   docker-compose -f docker-compose-multitenant.yml up -d --scale app=10
+# Example: Start the stack and expose the app on host port 10000
+#   INVENTAR_HTTP_PORT=10000 docker-compose -f docker-compose-multitenant.yml up -d
