+I you want to see the examples running, do this from two shells (current directory is the root of the `commander` repo):
+
+```bash
+# shell 1
+cargo run --example simple_host
+
+# shell 2
+cargo run --example simple_client

 ### Nextgen
 I am currently looking into using the rsa crate: `rsa = { version = "0.9", features = ["sha2", "pem"] }` for simple encryption/decrypting and message signing. More on this later.
