 The modules in this directory define [`google_monitoring_dashboard`](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/monitoring_dashboard) resources in a repeatable structured way.
 
+This module itself creates a dashboard that cleans up defaulted no-op changes.
+
 - The [Service](service/README.md) and [Job](job/README.md) modules define pre-configured dashboards for Cloud Run services and Cloud Run jobs, respectively.
 - The [`cloudevent-receiver`](cloudevent-receiver/README.md) module defines a pre-configured dashboard for a Cloud Run-based event handler receiving events from a `cloudevent-trigger`.
 - The modules in [`./widgets`](widgets/) define the widgets used by the dashboards, in a way that can be reused to create custom dashboards.
+
+```hcl
+// Call module to generate cleaned up json
+module "dashboard" {
+  source = "chainguard-dev/common/infra//modules/dashboard"
+
+  object = {
+    displayName      = "Elastic Build"
+    labels           = { "elastic-builds" : "" }
+    dashboardFilters = []
+
+    mosaicLayout = {
+      columns = module.width.size
+      tiles   = module.layout.tiles,
+    }
+  }
+}
+```
+
+The dashboard resource should now diff properly.
