+## Deploying Applications
+
+You can either install your application in `apps` for REST-Python to serve them, or deploy them with a separate server (e.g., NodeJS).  REST-Python supports cross-domain responses to REST and Websocket requests to facilitate dual- or multi-server configurations to completely decouple the REDHAWK environment from the web application environment.  (See [Docker-REDHAWK's](http://github.com/GeonTech/docker-redhawk) `geontech/redhawk-webserver` image.)
