I might have missed something, but the page is very simplistic and assumes you know what Matrix is and how to use this; a lot of time is spent on the installation through different means, but none how to use the server itself, either by use of a client?
You probably would want element.
I think conduit's page is doing the right thing. It doesn't really assume you know what matrix is, but rather assumes you're smart enough to click on a link if you don't know.
