INSTALL is a text file, you just need to open it with any text editor (notepad.exe would do fine). If you are on Windows, just right click on it and select [b]open with[/b] and select a program. Or open the program first and then open the file 'INSTALL'.
Or I can save you the trouble and just reproduce them right here, like so:
`zenphoto installation instructions
-------------------------------------------------`
`1. Get the files in the zenphoto.zip or zenphoto.tar.gz package on to your
server somehow (FTP, SSH, wget, tar -xzvf .., etc.)
(You may want to do step 2 first)`
`2. Go to http://www.yoursite.com/zenphoto/zen/setup.php and follow the
simple instructions.`
`(No, it's not really a 2 step install. There are 4 more steps in step 2...)`
Good luck.
