+@deftp {Data Type} nginx-vhost-configuration
+Data type representing the configuration of an nginx virtual host.
+This type has the following parameters:
+
+@table @asis
+@item @code{http-port} (default: @code{80})
+Nginx will listen for HTTP connection on this port.  Set it at @code{#f} if
+nginx should not listen for HTTP (non secure) connection for this
+@dfn{virtual host}.
+
+@item @code{https-port} (default: @code{443})
+Nginx will listen for HTTPS connection on this port.  Set it at @code{#f} if
+nginx should not listen for HTTPS (secure) connection for this @dfn{virtual host}.
+
+Note that nginx can listen for HTTP and HTTPS connections in the same
+@dfn{virtual host}.
+
+@item @code{server-name} (default: @code{(list 'default)})
+A list of server names this vhost represents. @code{'default} represents the
+default vhost for connections matching no other vhost.
+
+@item @code{root} (default: @code{"/srv/http"})
+Root of the website nginx will serve.
+
+@item @code{index} (default: @code{(list "index.html")})
+Index files to look for when clients ask for a directory.  If it cannot be found,
+Nginx will send the list of files in the directory.
+
+@item @code{ssl-certificate} (default: @code{"/etc/nginx/cert.pem"})
+Where to find the certificate for secure connections.  Set it to @code{#f} if
+you don't have a certificate or you don't want to use HTTPS.
+
+@item @code{ssl-certificate-key} (default: @code{"/etc/nginx/key.pem"})
+Where to find the private key for secure connections.  Set it to @code{#f} if
+you don't have a key or you don't want to use HTTPS.
+
+@item @code{server-tokens?} (default: @code{#f})
+Whether the server should add its configuration to response.
