+#### Configuring the JSON Module
+
+By default, zencoder-py uses the built-in `json` module, but you can optionally configure it to use `simplejson` by setting the `ZENCODER_PY_JSON_MODULE` environment variable to `simplejson`. Note that zencoder-py will not install either module, it must already be installed.
