1. Extract files from the ZIP.
  2. Upload all the extracted files to your hosting space. 
  3. Setup permissions to writable for the following files and directories:
     Files: 
       settings.php (chmod 666)
     Directories:
       /uploads/  (chmod 777)
       /skins/export/ (chmod 777)
       /skins/ (chmod 777)
       /pdf/ (chmod 777)      
  4. If you don't already have a database created, create one using
     your host's provided tools. (You may use an existing database if
     you like, if you have one.) Also be sure you've set up a mysql 
     username and given the username access to this database.
  5. Using your web browser, visit /install/index.php (in the directory you
     uploaded it to).   
  6. Follow the instructions on screen, supplying your database info
     and creating an administrative username and password -- be sure to
     remember your password.
  7. Once the installation is complete, you must delete the /install/ directory, as it can be a security risk.
