+	  Dehydrated is a client for signing certificates with an
+	  ACME-server (e.g. Let's Encrypt) implemented as a relatively
+	  simple (zsh-compatible) bash-script. This client supports
+	  both ACME v1 and the new ACME v2 including support for
+	  wildcard certificates!
+
+	  To use this script in Buildroot:
+	    - Create /etc/dehydrated/domains.txt
+	    - Make sure that "dehydrated -c" is called regularly, e.g.
+	      from cron.
+	    - Make sure /etc/dehydrated is writable.
+	    - Configure the webserver to export the WELLKNOWN directory
+	      (/var/www/dehydrated) as /.well-known/acme-challenge
+	    - Configure the webserver to use the certificates under
+	      /etc/dehydrated/certs/<domain>
+	    - Register a HOOK to reload the webserver after the
+	      certificates have been renewed.
+
+	  You probably need to install a custom /etc/dehydrated/config
+	  with the rootfs overlay.
