-## Deploying the PipeBackend with the BindBackend
-Included with the PDNS distribution is the example.pl backend which has knowledge of the example.com zone, just like the BindBackend. To install both, add the following to your `pdns.conf`:
-
-```
-launch=pipe,bind
-bind-example-zones
-pipe-command=location/of/backend.pl
-```
-
-Please adjust the [`pipe-command`](#pipe-command) statement to the location of the unpacked PDNS distribution. If your backend is slow, raise [`pipe-timeout`](#pipe-timeout) from its default of 2000ms. Now launch PDNS in monitor mode, and perform some queries. Note the difference with the earlier experiment where only the BindBackend was loaded. The PipeBackend is launched first and thus gets queried first. The sample backend.pl script knows about:
-
--   webserver.example.com A records pointing to 192.0.2.4, 192.0.2.5, 192.0.2.6
--   www.example.com CNAME pointing to webserver.example.com
