 To run the service, you will also need to run the [datdot-substrate](https://github.com/playproject-io/datdot-substrate) chain

-We are using scenarios to debug the flow. This scenario is part of our first milestone (Phase 1).
+##### `cargo build -p datdot-node --release`
 
-1. To run the chain and the service process at once use the command `node cli.js` (recommended)
+## Running
+This scenario is part of our first milestone (Phase 1). To run it together with the chain, use:
 
-2. To run the chain and the service process individually, use:
+##### `node cli.js`
 
-$`DEBUG=*,-hypercore-protocol node lab/scenarios/mvp-1.js` (for [datdot-service](https://github.com/playproject-io/datdot-service))
-$`.target/release/datdot-node --dev` ([datdot-substrate](https://github.com/playproject-io/datdot-substrate))
+To re-run the scenario, you will need to each time purge the chain storage using `./target/release/datdot-node purge-chain --dev`.
 
-3. To re-run the scenario, you will need to purge the chain storage (for `./target/release/datdot-node purge-chain --dev`)
+If you want, you can also run the chain and the service as independent processes:
+

+
+##### `DEBUG=*,-hypercore-protocol node lab/scenarios/mvp-1.js`
+
+Chain

+##### `.target/release/datdot-node --dev`
