 Go to your project's **Settings** page and copy the API secret. In your terminal, export it as an environment variable:
 
 ```bash
-export N0DES_API_SECRET=<your-api-secret>
+export IROH_SERVICES_API_SECRET=<your-api-key>
 ```
 
 ### 2. Run the diagnostics client
 
 Clone the repository and run the `net_diagnostics` example:
 
 ```bash
-git clone https://github.com/n0-computer/iroh-n0des.git
-cd iroh-n0des
-cargo run --example net_diagnostics --features net_diagnostics,client_host
+git clone https://github.com/n0-computer/iroh-services.git
+cd iroh-services
+cargo run --example net_diagnostics --features net_diagnostics,client_host --features="example"
 ```
 
 Leave this terminal open. The example connects to n0des, grants the diagnostics capability to your project, and waits for incoming diagnostics requests.
