 ## Running the Test
 
-First, compile the WASM binary and start the local HTTP server. Refer to
-[Testing and Examples](../../README.md#Testing and Examples) in the repository
-README for details on how to do this. Open the two clients, the sender and
-receiver.
+1. First, compile the WASM binary and start the local HTTP server. Refer to
+   [Testing and Examples](../../README.md#Testing and Examples) in the
+   repository README for details on how to do this. Open the two clients, the
+   sender and receiver.
 
-First start the network using the wasm-network.sh script in integration. This
-will start all the gateways and client registrar using localhost as their public
-IP addresses and the NDF will be provided by the permissioning server rather
-than downloaded from a gateway.
+2. Next, start the network using the `run.sh` script in the `wasmTest` directory
+   in integration. This will start all the gateways and client registrar using
+   localhost as their public IP addresses and the NDF will be provided by the
+   permissioning server rather than downloaded from a gateway.
 
-Once rounds are running, on the receiver webpage, navigate to the results folder
-in integration and select the `permissions-ndfoutput.json` file. Doing this will
-start the client. Once the client generates keys and joins the network, it will
-prompt its contact file for download. Copy the contents of this file into the
-`recipientContactFile` const in `sender.html`.
+3. Once rounds are running, on the receiver webpage, navigate to the results
+   folder in integration and select the `permissions-ndfoutput.json` file. Doing
+   this will start the client. Once the client generates keys and joins the
+   network, it will prompt its contact file for download. Copy the contents of
+   this file into the `recipientContactFile` const in `sender.html`.
 
-On the sender webpage (make sure to refresh the page), select the NDF file as
-described for the recipient above. This will start the sender client. Once it
-generates its keys and joins the network, it will add the receiver client as a
-partner, they will exchange requests and confirmations, and finally, the sender
-will send an E2E message to the recipient.
