# tmp-proc-zipkin
`tmp-proc-zipkin` provides an example of using `tmp-proc` to launch dockerized
Zipkin in integration tests.
It provides an instance of [Proc][1] for launching the Zipkin image, and also
provides an instance of [Conn][2] that simplifies opening connections to the
launched Zipkin service from tests that use `tmp-proc`.
