 Building TVA (Cluster)
 ============
 In order to use the framework in the LAN or WAN settings, we need to replicate the previous steps for each machine in the computing parties cluster. Make sure to use same paths on each machine when cloning and building the repository. Once, we have TVA working on every machine, we can now start building the cluster. For this we need to do the following:
-- Make sure that machines have pair wise SSH access to each other. This step depends on the cloud service provider as firewall settings and defaults are different.
-- Modify the `./etc/hosts` file on each machine to include other computing parties with names in the format `machine-i` for LAN and `machine-wan-i` for WAN.
-- Build the executables using either the semi-honest `semi` or the malicious protocol `mal` on each machine using the following script.
+- Make sure that machines have pair wise SSH access to each other (including themselves). This step depends on the cloud service provider as firewall settings and defaults are different. Incoming traffic should be allowed on all machines.
+- Modify the `./etc/hosts` file on each machine to include other computing parties with names in the format `machine-i` for LAN and `machine-wan-i` for WAN. Also add an alias for localhost.
+- Build the executables on any of the machines using either the semi-honest `semi` or the malicious protocol `mal` on each machine using the following script.
 ```
 cd scripts
 ./build_experiments.sh semi  # mal
