To install my quest, QUEST1, you need to place the files
QUEST1.QDT and QUEST1.QST in your ARENA directory.

Then edit your quests.anc file, a text file in the Arena
directory, and add to the end of the file a line with the 
word 'quest1'. The only thing on that line should be the 
word 'quest1'.

To uninstall this quest, simply delete that line from
the quests.anc file in your arena directory.
