+Azure AppServices (Web, API, Functions) DataDog monitors
+========================================================
+
+How to use this module
+----------------------
+
+```
+module "datadog-monitors-azure-app-services" {
+  source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/azure/app-services?ref={revision}"
+
+  message     = "${module.datadog-message-alerting.alerting-message}"
+  environment = "${var.environment}"
+}
+```
+
+Purpose
+-------
+Creates a DataDog monitors with the following checks :
+
+* Response time
+* Memory usage count
+* HTTP 404 errors
+* HTTP 50x errors
+* HTTP 20x rate
+
+Inputs
