[edit] Web server on DD-WRT
<Kong> has written a basic guide to running your own personal cloud server on your R7000, using the application Pydio along with the built-in web server, lighttpd. See Using The Integrated Webserver for guidance on setting up USB storage, enabling the built-in web server and installing a sample web application, in this case Pydio.
