-## Try it out
-
-Either using the `demo/docker-compose.yaml` or when in the `nix-shell`, you can
-start a demo scenario with three parties using the following commands each in a
-separate shell:
-
-``` sh
-$ cabal exec mock-chain
-```
-
-``` sh
-$ cabal exec hydra-node -- --node-id 1 --api-port 4001 \
-  --port 5001 --peer "localhost:5002" --peer "localhost:5003" \
-  --me "demo/alice.sk" --party "demo/bob.vk" --party "demo/carol.vk"
-```
-
-``` sh
-$ cabal exec hydra-node -- --node-id 2 --api-port 4002 \
-  --port 5002 --peer "localhost:5001" --peer "localhost:5003" \
-  --me "demo/bob.sk" --party "demo/alice.vk" --party "demo/carol.vk"
-```
-
-``` sh
-$ cabal exec hydra-node -- --node-id 3 --api-port 4003 \
-  --port 5003 --peer "localhost:5001" --peer "localhost:5002" \
-  --me "demo/carol.sk" --party "demo/alice.vk" --party "demo/bob.vk"
-```

-Then you can interact with any of the three `hydra-node` instances using `ws`
-and connecting to the individual port, e.g. to initiate a head via alice's
