 ## What the demo can do if you run it.
 
-There is a demo program that takes the location of a chutney directory or a
-tor directory. If it finds one, it reads the directory info from
-disk, builds a random three hop circuit, and sends a request for
-http://www.torproject.org:80/.  Then it displays the answer on stdout.
+It can act as a SOCKS proxy that uses the Tor network.  (Not a very
+secure or anonymous one!)  It knows how to download directory
+information and how to load it from cache, but it doesn't try to
+download more than one directory per run.
 
-Example:
-   % cargo run -- --tor-dir ~/.tor/
+To try it out, run the demo program in client-demo.   It will open a
+SOCKS proxy on port 9150.
 
-Remember that rust builds without optimizations by default, so it
-may be a bit slow.  You can try an optimized build with
-   % cargo run --release -- --tor-dir ~/.tor/
+    % cargo run --release
+
+Again, do not use this program if you need anonymity, privacy, security,
+or stability.
