+This package provides everything needed to interact with the unstable OpenTelemetry Logs Bridge API, including all TypeScript interfaces, enums, and no-op implementations. It is intended for use both on the server and in the browser.
 
-The logs API is considered alpha software and there is no guarantee of stability or long-term support. When the API is stabilized, it will be made available and supported long-term in the `@opentelemetry/api` package and this package will be deprecated.
+**Note: This module defines a log backend API. The API is not intended to be called by application developers directly.
+It is provided for logging library authors to build log appenders, which use this API to bridge between existing
+logging libraries and the OpenTelemetry log data model.**
