Uninstall nginx.
+## Adding more information
+
+This plugin also provides an `office_hours_additional_information` directive
+that lets you add informative HTML to the page that shows when outside
+office hours.
+
+```
+office_hours_additional_information "<h1>Additional Information></h1>
+<p>Please do not email us asking to open the website 24/7. Send all complaints to friendship.quest/@ruben</p>"
+```
+
## What you will need to get started
* [astyle][astyle]: Used to format the code
## Further Improvements
+* Add support for double shifts in the same day
+* Add support for serving custom HTML when server is closed
* Add support for timezones (currently only GMT)
* Add support for public holidays
* Add support to respect the time zone of the visitor and not just the
server
-* Add support for double shifts in the same day
