 ### Alert rules
 
+The following endpoints can be used to manage both alert rules and recording rules. To create a recording rule, include a `record` block in your request instead of a `condition` field.

+**Example request for new recording rule:**
+
+Recording rules allow you to pre-compute frequently used or computationally expensive expressions and save the results as new time series data. To create a recording rule instead of an alert rule, include a `record` block in your request.
+
+The `record` block contains the following fields:
+
+- `metric`: The name of the new metric to create
+- `from`: The `refId` of the query whose value will be used for the recording
+- `target_datasource_uid`: The UID of the data source where the metric will be written
