++++++++
+
+.. note:: Try to outline a sample subscription creation process.
+
+* Prerequisites: Registered Merchant with API credentials configured for a Service.
+
+1. The :term:`merchant` configures a API access key for others services.
+2. Have an external service to create a new subscription against
+    BillingStack when a new :term:`resource` is created in a system.
+
+3. Subscription is either created towards an existing:term:`customer` or
+    if the :term:`merchant` has a setting configured to allow :term:`customer`
+    created if the given customer doesn't exist it will be created along with
+    subscription.
+4. When a subscription is created we're ready to receive events from a system.
