+## Generic Azure Resource
+You can declare to scrape a generic Azure resource via the `Generic` resource type.
+
+The following fields need to be provided:
+- `resourceUri` - The uri of the Azure resource to scrape.
+- `filter` - The filter to use to have fine-grained metrics. Example: `EntityName eq 'orders'`
+
+Promitor simplifies defining resource uris by using the subscription & resource group defined in `azureMetadata` so that your configuration is small & readable.
+
+Example:
+```yaml
+name: demo_generic_queue_size
+description: "Amount of active messages of the 'myqueue' queue (determined with Generic provider)"
+resourceType: Generic
+# Will scrape subscriptions/<sub>/resourceGroups/<rg>/providers/Microsoft.ServiceBus/namespaces/promitor-messaging
+# Where 'sub' & 'rg' are coming from azureMetadata
+resourceUri: Microsoft.ServiceBus/namespaces/promitor-messaging
+filter: EntityName eq 'orders'
+azureMetricConfiguration:
+  metricName: ActiveMessages
+  aggregation: Total
+```
