 - for configuring, extending, and embedding Cockpit you need to coarsely understand the components of it
 - this: simplest structure, what I just showed you and what you will most probably see the first time you try it
-- browser only speaks HTTP and WebSocket, so you always need a web server, cockpit-ws
 - all components in cockpit communicate to each other via a JSON protocol on standard pipes, usually stdio
 - this provides a lot of flexibility and extensibility, as we'll see shortly
+- browsers and JS only speak HTTP and WebSocket, and can't directly talk to Linux system APIs
+- so you always need a web server somewhere, cockpit-ws
 - ws roles: communicate with the browser for getting credentials: login page, krb negotiation, client cert
 - ws: deliver HTML/js content, connects JSON protocol on the WebSocket to pipes to the other components; runs as unprivileged system user
