 ## OpenTelemetry Python
 
-The Python [OpenTelemetry](https://opentelemetry.io/) implementation.
+This page describes the Python [OpenTelemetry](https://opentelemetry.io/) implementation. OpenTelemetry is an observability framework for cloud-native software.
 
 ## Getting started
 
-OpenTelemetry's goal is to provide a single set of APIs to capture distributed traces and metrics from your application and send them to an observability platform. This project allows you to do just that for applications written in Python.

 The `opentelemetry-sdk` package is the reference implementation of the API.
 
 Libraries that produce telemetry data should only depend on `opentelemetry-api`,
 and defer the choice of the SDK to the application developer. Applications may
 depend on `opentelemetry-sdk` or another package that implements the API.
