+
+# More Hosts!
+
+Hark at the hosts in `~/.ssh/config`:
+
+```sh
+Host soft
+    HostName soft.dmz.rs
+    Port 2222
+	User ghost
+	IdentityFile ~/.ssh/id_rsa
+Host krov
+	HostName krov.dmz.rs
+	User malin
+Host kralizec
+	HostName dmz.rs
+	User root
+Host laka
+	HostName 192.168.0.50
+	IdentityFile ~/.ssh/id_rsa
+```
+
+***
+
+## Hosts in toml
+
+
+```toml
+[webby]
+nginx12
+
+[webby:vars]
+user=alice
+```
+
+This is easy to read, but breaks standards.
+
+***
+
+`ansible-play -i hosts.toml playbooks/mmcli`
+
+***
+
+Better to stick with standards, even if you can't read it!
