 ```
 sudo wg set wg0 peer ${two_pubkey:?} endpoint ${two_public_ip:?}:${two_port:?} allowed-ips ${two_wg_ip:?}/32

 if we also want to be able to refer to the host by an easy to remember name rather than just an IP, we can also add it to `/etc/hosts`
+```
+echo -e "${two_wg_ip:?}\t${two_hostname}.wg.alemor.org" >> /etc/hosts
+```
