+
+There are 5 Go services total: [3 “microservices”][domain-services] responsible for
+domain data, and [2 services][temporal-services] which interact with Temporal.
+
+One of those services is the “starter” which clients pass data to. The “Starter”
+[accepts all input data, starts a workflow, and immediately returns][starter]
+some key data, such as the workflow ID and various primary keys of the created
+data. This is actually a good user experience, because clients hear back from
+the server as soon as possible, while the backend can chug along with complex
+asynchronous work.
+
+Once the workflow has started and been received by the Temporal Cluster, the 
+message will be dispatched to our [“Worker”][worker], which has
+[registered][register] a [workflow definition][workflow-definition], as well as
+a [controller][controller] for making the network requests for of our 
+[3 activities][execute-activity].
