+
+## Overview
+
+This module contains functionality for aggregating status information about components. Used by extensions that
+implement the `componentstatus.Watcher` interface for collecting status information about the internal status of all
+components inside the collector.
+
+### History
+
+`pkg/status` was originally developed for the `healthcheckv2extension`. It provided a generic way of aggregating
+status information for components. Other extensions that need to implement the `componentstatus.Watcher` can now use
+the same implementation `healthcheckv2extension` uses.
