The *OpenCensus Datadog Trace Exporter* is a trace exporter that exports data to [Datadog](https://www.datadoghq.com/).

## Quickstart

### Prerequisites

Datadog collects traces using a local agent, which forwards them to the Datadog automatic tracing. Instructions for setting up the agent can be found [in the Datadog docs](https://docs.datadoghq.com/agent/?tab=agentv6).

### Hello Datadog
