 ### Run the application for development
 
 Since Observer Web uses the OTP distribution, it is required to have a name when running.
-```
+
+```console
 elixir --sname observer -S mix run --no-halt dev.exs
 ```
 
 Now you can visit [`localhost:4000/observer`](http://localhost:4000/observer) from your browser.

 ### Run multiple nodes with Metric Hub configuration
 
 1. Start the nodes
 
 Open a new terminal (Terminal 1) and run the application in `observer` mode:
-```
+
+```console
 export PORT=4000
 export OBSERVER_WEB_TELEMETRY_MODE=observer
 elixir --sname observer --cookie cookie -S mix run --no-halt dev.exs
 ```
 
 Open a new terminal (Terminal 2) and run the application in `broadcast` mode:
-```

+```console
 export PORT=4001
 export OBSERVER_WEB_TELEMETRY_MODE=broadcast
 elixir --sname broadcast --cookie cookie -S mix run --no-halt dev.exs

 To verify everything is working properly:
 
- * Visit [`localhost:4000/observer/metrics`](http://localhost:4000/observer/metrics) in your browser to confirm 
-   the application is running in `observer` mode.
- * Visit [`localhost:4001/observer/metrics`](http://localhost:4001/observer/metrics) to confirm the application

 You can now explore the `observer` mode, checking that the data is persisted even if the other app in
 broadcast mode restarts.
