## About this project

This is the JavaScript version of [OpenTelemetry](https://opentelemetry.io/), a framework for collecting traces and metrics from applications.

## Quick start

### Application Owner

To get started tracing your own application, see the [Getting Started Guide](getting-started/README.md). For more information about automatic instrumentation see [@opentelemetry/node][otel-node], which provides auto-instrumentation for Node.js applications. If the automatic instrumentation does not suit your needs, or you would like to create manual traces, see [@opentelemetry/tracing][otel-tracing]

### Library Author

If you are a library author looking to build OpenTelemetry into your library, please see [the documentation][docs]. As a library author, it is important that you only depend on properties and methods published on the public API. If you use any properties or methods from the SDK that are not officially a part of the public API, your library may break if an [Application Owner](#application-owner) uses a different SDK implementation.

## Supported Runtimes

| Platform Version | Supported                                       |
