+# MeetEasier - Custom Fork for Raspberry Pi Official Touchscreen
 
-Because why pay money for something you can do yourself?
 
-## Description
 
+## Description
+This is a customised fork of "MeetEasier" https://github.com/danxfisher/MeetEasier.
 MeetEasier is a web application that visualizes meeting room availability.  It works using Exchange Web Services (EWS) with Exchange room lists in Office 365.
 
-![Mockup 1](mockups/mockup-1.jpg)
+This particular fork adds additional functionality (e.g. buttons for making bookings, extending bookings and ending meetings) and hides some options depending on environment variables (set in the .env files)
