The *OpenCensus Instana Trace Exporter* is a trace exporter that exports
data to Instana. [Instana](http://www.instana.com/) is a distributed
tracing system.

## Quickstart

### Prerequisites

[Instana](http://www.instana.com/) forwards traces exported by applications
instrumented with Census to its backend using the Instana agent processes as proxy.
If the agent is used on the same host as Census, please take care to deactivate
automatic tracing.
