+# Minimal Example
+Via `docker-compose` we can simulate an environment with three services all contributing to the boundary type `Foo`.
+
+```
+docker-compose up
+```
+
+The gateway will then be hosted on `http://localhost:8082/query`, be sure to point a GraphQL client to this address.
+
+```graphql
+{
+  randomFoo {
+    nodejs
+    graphGophers
+    gqlgen
+  }
+}
+```
+
+_Note: each field is resolved by each different service here._
