+## Ques
+
+A que is a multi-consumer, multi-producer channel available anywhere you
+have a network connection. If you are familiar with Go channels, they
+are pretty much the same thing. Put some values in one end, and take
+them out the other end at a different time, or in a different process.
+
+Ques are created dynamically for every HTTP request you make. Here we
+use the `que` client to create a new que at the path `example/new-que`:
+
+ que example/new-que
+
+The `que` client is useful, but you can use anything to make the HTTP
+request, for example here's the same thing with curl:
+
+ curl https://que.run/example/new-que
+
+These requests will block until a value is placed on the other
+end. Let's do that now. In a separate terminal:
+
+ echo "hello world" | que example/new-que -
+
+This tells the `que` client to read the value from `stdin` and then send
+it to `example/new-que`. Or with curl:
+
+ curl https://que.run/example/new-que -d "hello world"
+
+This will succeed immediately and send the string "`hello world`" over
+the channel, which will be received and printed by the listener in the
+other terminal.
+
+You can have as many producers and consumers attached to a channel as
+you want.
+
+## Namespaces
+
+Ques are organized into namespaces, identified by the first fragment of
+the path. In the above commands we used `example` as the namespace, but
+you can use whatever you want.
+
+Except, there is one special namespace `_` which is reserved for
+internal use only. You can't write to the `_` namespace.
+
+Namespaces are normally public, and anyone can write and read to
+them. The `Pro` version allows you to reserve namespaces and add
+authentication.
+
+## Events
+
+Just reading and writing data isn't very exciting, so let's throw in
+some events. We can very quickly put together a job processor.
+
+ que example/new-que --then "./worker.sh '\msg'"
