+1. Make sure nix is installed and IOHK binary cache is configured [nix setup] (https://github.com/input-output-hk/cardano-sl/blob/develop/docs/how-to/build-cardano-sl-and-daedalus-from-source-code.md#nix-build-mode-recommended)
+2. To generate a script that will launch the demo cluster run `nix-build -A demoCluster -o launch_demo_cluster`
+3. To generate a script that will launch demo cluster suitable for Daedalus development, run `nix-build -A demoClusterDaedalusDev -o launch_demo_cluster`
+4. To launch cluster, run `./launch_demo_cluster`
+5. To stop, hit `ctrl-c` and it will terminate all the nodes.
+6. A `state-demo` state folder will be automatically created relative to your current
+   working directory.
+  * Logs will be found in `state-demo/logs`
+  * TLS certs/keys will be found in `state-demo/tls`
+  * 11 genesis wallets will be pre-loaded with 37 million Ada each

+* `launch/demo-nix.sh` - run demo cluster using nix with 4 core nodes, 1 relay, 1 wallet in background
 * `launch/demo-with-wallet-api.sh` - run nodes in `tmux`-session, with enabled wallet web API (3 nodes by default).
 * `launch/kill-demo.sh` - kill `tmux`-session with running nodes.
