 [API Management](https://azure.microsoft.com/en-us/services/api-management/) is an Azure Service for publishing, managing, securing and monitoring APIs. It can be deployed along with your Serverless function app by specifying its configuration in `serverless.yml`. Here is a basic example of how to configure API Mangement:
 
-## Simple Handler
+## Simple Configuration
+Simply by setting `apim: true` in your configuration a consumption based APIM resource will automatically be deployed to Azure.  By default it will create a API with path of `/api` in your APIM instance and will map all operations defined in the serverless yaml to your function app
 
 ```yaml
 service: greeter
 
+provider:
+  prefix: greeter
+  name: azure
+  # Default to West US, allow for command line arg --region to override
+  region: ${opt:region, 'westus'}
+  # Default to dev, allow for command line arg -- stage to override
+  stage: ${opt:stage, 'dev'}
+  # Azure subscription ID for deployment
+  subscriptionId: 00000000-0000-0000-0000-000000000000
+
+  # Start of your API Management configuration
+  apim: true
+
+plugins:
+  - serverless-azure-functions
+
+functions:
+  hello:
+    handler: src/handlers/hello.handler
+    events:
+      - http: true
+        x-azure-settings:
+          methods:
+            - GET
+          authLevel : function
+      - http: true
+        x-azure-settings:
+          direction: out
+          name: res
+```
+
+## Full Configuration
+In this example you can see the configuration support is quite verbose.  You have the ability to create multiple APIs and Backends as well as associate an operation to a specific api/backend.  If the operation is not specifically defined it will default to the first API / Backend that has been defined.
