+### Ingest delta temporality OTLP metrics
+
+OpenTelemetry supports two temporalities, [Delta and Cumulative](https://opentelemetry.io/docs/specs/otel/metrics/data-model/#temporality).
+By default, only the cumulative metrics can be ingested via OTLP endpoint in Cortex.
+To enable the ingestion of OTLP metrics with delta temporality, set the `distributor.otlp.allow-delta-temporality` flag to `true`.
+
+### Enable `__type__` and `__unit__` label
+
+The `__type__` and `__unit__` labels are added to OTLP metrics if `distributor.otlp.enable-type-and-unit-labels` is set to `true`.
+This flag is disabled by default.

 ### Configure promote resource attributes per tenants
 
 The `promote_resource_attributes` is a [runtime config](./overrides-exporter.md) so you can configure it per tenant.
