 This creates the `.piedesaint` folder that you can inspect and configure (it contains a default shortlived and self-signed SSL key/certificate pair and some additional configuration in [YAML](http://en.wikipedia.org/wiki/YAML) format).
 
 By default the configuration will serve the current directory, unless a list of folders is specified. If you want to serve a different folder or set of folders, just edit the configuration.
 
+Host can be set via:
+
+  $ sug set_host [host IP]
+
+This is useful/required so that the certificate is created with the correct IP and systems can validate it correctly.
+
 After this, whenever you want to serve the files/directories, just execute:
 
 	$ sug
 
 Alternatively, by editing `.piedesaint/config`, you can disable compressed folders (`:tar: false`), the need for Basic Authorization credentials (using an empty `:username:`) or the SSL behaviour (using an empty `:key:`).
