 The Elastic Distribution of OpenTelemetry Python (EDOT Python) is a customized version of [OpenTelemetry Python](https://opentelemetry.io/docs/languages/python).
 EDOT Python makes it easier to get started using OpenTelemetry in your Python applications through strictly OpenTelemetry native means, while also providing a smooth and rich out of the box experience with [Elastic Observability](https://www.elastic.co/observability). It's an explicit goal of this distribution to introduce **no new concepts** in addition to those defined by the wider OpenTelemetry community.
