 The `opentelemetry-sdk` gem provides the reference implementation of the OpenTelemetry Ruby interfaces defined in the `opentelemetry-api` gem. That is, it includes the *functionality* needed to collect, analyze, and export telemetry data produced using the API.
 
-Generally, Ruby *applications* should install `opentelemetry-sdk` (or other concrete implementation of the OpenTelemetry API). Using the SDK, an application can configure how it wants telemetry data to be handled, including which data should be persisted, how it should be formatted, and where it should be recorded or exported. However, *libraries* that produce telemetry data should generally depend only on `opentelemetry-api`, deferring the choise of concrete implementation to the application developer.
