+
+# azurerm\_availability\_set
+
+Create an availability set for virtual machines.
+
+## Example Usage
+
+```
+resource "azurerm_resource_group" "test" {
+    name = "resourceGroup1"
+    location = "West US"
+}
+
+resource "azurerm_availability_set" "test" {
+    name = "acceptanceTestAvailabilitySet1"
+    location = "West US"
+    resource_group_name = "${azurerm_resource_group.test.name}"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) Specifies the name of the availability set. Changing this forces a
+    new resource to be created.
+
+* `resource_group_name` - (Required) The name of the resource group in which to
+    create the availability set.
+
+* `location` - (Required) Specifies the supported Azure location where the resource exists. Changing this forces a new resource to be created.
+
+* `platform_update_domain_count` - (Optional) Specifies the number of update domains that are used. Defaults to 5.
+
+* `platform_fault_domain_count` - (Optional) Specifies the number of fault domains that are used. Defaults to 3.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - The virtual AvailabilitySet ID.
