+Meeting Room Booking System
+http://mrbs.sourceforge.net/
+-------------------------------
+
+The Meeting Room Booking System (MRBS) is a PHP-based application for
+booking meeting rooms (surprisingly!). I got annoyed with the piles of books
+which were being used to book meetings. They were slow, hard to edit and only
+at the reception desk. I thought that a nice web-based system would be much
+nicer.
+
+Some parts of this are based on WebCalender 0.9.4 by Craig Knudsen
+(http://www.radix.net/~cknudsen/webcalendar/) but there is now very little
+which is similar. There are fundamental design goal differences between
+WebCalendar and MRBS - WC is for individuals, MRBS is for meeting rooms.
+
+------
+To Use
+------
+See the INSTALL file for installation instructions.
+
+Once it's installed try going to http://yourhost/mrbs/
+
+If you're using the default authentication type ('db') the first thing you'll
+be prompted to do is to create an admin user.  Once you've done that you'll
+need to login using the credentials you've just specified.
+
+Once you have logged in as an administrator you can click on "Rooms" and
+create first an "Area", and then a "Room" within that area.
+
+There are other ways to configure authentication in MRBS, see the
+file AUTHENTICATION for a more complete description.
+
+It should be pretty easy to adjust it to your corporate colours - you can
+modify the themes under "Themes" or (preferably) copy an existing theme
+to a new directory and modify the new theme.
+
+See LICENSE for licensing info.
+
+See NEWS for a history of changes.
+
+See AUTHENTICATION for information about user authentication/passwords.
