 ## Testing libswarm with swarmd
 
 Libswarm ships with a simple daemon which can control all machines in your distributed
 system using a variety of backend adaptors, and exposes it on a single, unified endpoint.
 
-Currently swarmd uses the standard Docker API as its frontend, which means any tool which speaks
-Docker can control swarmd transparently: dokku, flynn, deis, docker-ui, shipyard, fleet,
-mesos... and of course the Docker client itself.
-
-*Note: in the future swarmd will expose the Docker remote API as "just another backend", and
-expose its own native API as a frontend.*
-
 Usage example:
 
-```
-./swarmd tcp://localhost:4242 &
-docker -H tcp://localhost:4242 info
-```
 
-You can listen on several frontend addresses, using any address format supported by Docker.
-For example:
+Run swarmd without arguments to list available backends:
 
 ```
-./swarmd tcp://localhost:4242 tcp://0.0.0.0:1234 unix:///var/run/docker.sock
+./swarmd
 ```
 
-## Backends
-
-Libswarm supports the following backends:
-
-### Debug backend
-
-The debug backend simply catches all commands and prints them on the terminal for inspection.
-It returns `StatusOK` for all commands, and never sends additional data. Therefore, docker
-clients which expect data will fail to parse some of the responses.
-
-Usage example:
+Pass a backend name as argument to load it:
 
 ```
-./swarmd --backend debug tcp://localhost:4242
+./swarmd fakeclient
 ```
 
-### Simulator backend
-
-The simulator backend simulates a docker daemon with fake in-memory data. 
-The state of the simulator persists across commands, so it's useful to analyse
-the side-effects of commands, or for mocking and testing.
-
-Currently the simulator only implements the `containers` command. It can be passed
-arguments at load-time, and will use these arguments as a list of containers.
-
-For example:
+You can pass arguments to the backend, like a shell command:
 
 ```
-./swarmd --backend 'simulator container1 container2 container3' tcp://localhost:4242 &
-docker -H tcp://localhost:4242 ps
+./swarmd 'dockerserver tcp://localhost:4243'
 ```
 
-In this example the docker client should report 3 containers: `container1`, `container2` and `container3`.
+You can call multiple backends. They will be executed in parallel, with the output
+of each backend connected to the input of the next, just like unix pipelines.
 
-### Forward backend
-
-The forward backend connects to a remote Docker API endpoint. It then forwards
-all commands it receives to that remote endpoint, and forwards all responses
-back to the frontend.
-
-For example:
+This allows for very powerful composition.
 
 ```
-./swarmd --backend 'simulator myapp' unix://a.sock &
-./swarmd --backend 'forward unix://a.sock' unix://b.sock
-docker -H unix://b.sock ps
-```
-
-This last command should report 1 container: `myapp`.
-
-
-### Creating a new backend
-Create a simple my-backend.go:
-```
-func MyBackend() engine.Installer {
-	return &myBackend{}
-}
-
-func (f *computeEngineForward) Install(eng *engine.Engine) error {
-	eng.Register("mybackend", func(job *engine.Job) engine.Status {
-	job.Eng.Register("containers", func(job *engine.Job) engine.Status {
-			log.Printf("%#v", *job)
-			return engine.StatusOK
-		})
-		return engine.StatusOK
-	})
-	return nil
-}
-```
-
-Then edit backends.go, and add your backend:
-```
-...
-	MyBackend().Install(back)
-...
+./swarmd 'dockerserver tcp://localhost:4243' 'debug' 'dockerclient unix:///var/run/docker.sock'
 ```
