-# Nginx configurator (patent for that name is pending...)
+# Nginx cluster configurator - ncc
+
+Manages the local nginx configuration and replicates changes to a backup.
+
+## Features
+
+* Allows the editing of services and using a template for new ones. Makes sure
+  the configuration is valid before reloading the cluster (nginx).
+* Automatically obtains SSL certificates and replicates them to the cluster (dehydrated).
+* Will only make changes on the master server (keepalived).
 
 # TODO
+
 * Prepare config templates for nginx and dehydrated?
 * document dhparam.pem generation (`openssl dhparam -out ssl-dhparams.pem 4096` in /etc/autossl)
 * Limit current SSH keys to only config rsync and nginx reload
