  1. Unzip the downloaded zip file

  4. Rename the /includes/dist-configure.php and /admin/includes/dist-configure.php files to "configure.php" and make the files writable (so the install process can write your configuration information into them after you answer a few questions in the following steps).
  5. Also make the /cache and /logs folders writable. (You will be prompted about making other folders writable during installation)
  6. Follow the instructions that appear in your browser for installation.

If some of the terms used in these brief instructions are things you don't understand, there is a much more detailed set of instructions in the /docs/Implementation-Guide PDF.
