+`MAILER_URI` should be set to allow emails to be sent.
+
+Further you have to setup a Load Balancer (more in the Configuration section)
+
+## Configuration
+
+for this setup it is important to have either an 
+ingress server that does load balancing on paths
+or to expose the api on a different host.
+
+If you expose the api on a different host do not forget
+to change the API_HOST env variable on the ui 
+container to route the requests properly.
+
+
+# AWS Cloudfront Ingress
+
+both ui and api would run behind a load balancer.
+
+the default path should then be routed to the ui container
+and the /graphql path to the api container.
