+# Sites available
+
+Files in this folder are not referenced/loaded automatically. The intended
+purpose of this folder is to contain all server config files whether they
+are currently in use or not.
+
+So, for example this folder may contain:
+
+	example.com
+	example.com-original
+	otherdomain.com
+	newproject.com
+
+Where each file contains the server block(s) specific to that project.

+# Sites enabled
+
+Files in this folder **are** loaded automatically. The intended purpose of
+this folder is to contain symlinks to the folder `sites-available`.
+
+## Enabling a new site
+
+To enable a new site, link the config file to sites-enabled, and restart nginx.
+
+For example:
+
+	$ cd /etc/nginx/sites-available
+
+	... create newproject.com ...
+
+	$ cd /etc/nginx/sites-enabled
+	$ ln -s ../sites-available/newproject.com .
+
+	$ /etc/init.d/nginx reload
+	[....] Reloading nginx configuration: nginx.
+	$
+
+## Disabling a site
+
+To disable a site, remove the symlink from the sites-enabled folder, and restart
+nginx.
+
+For example:
+
+	$ cd /etc/nginx/sites-enabled
+	$ rm newproject.com
+
+	$ /etc/init.d/nginx reload
+	[....] Reloading nginx configuration: nginx.
+	$
