-Prerequisites:
+For installation instructions, please refer to:
 
-iTop requires
-- A web server running PHP 5.2.0 or higher, with PCRE, SESSION, php-xml, mysql, iconv, simplexml, hash, json and soap support.
-  If you wish to use LDAP authentication, then LDAP support must be enabled in PHP. 
-- A connection to MySQL 5.0 or higher database
-
-Web browser support:
-iTop is developed using FireFox 3.x+ and tested with IE 8+, Safari 5+ and Chrome.
-
-Installation:
-
-1. Unzip the distribution (be sure to unzip the subdirectories) and copy the
-   content of the "web" directory in your webserver's document root. If you
-   don't have direct access to the web server's file system, put the files
-   in a directory on your local machine and transfer the content of the
-   directory on your web server using, for example, ftp.
-
-2. Ensure that all the scripts have the appropriate owner (if PHP is running in
-   safe mode, having some scripts with an owner different from the owner of
-   other scripts will be a problem).
-   Check the access rights on the files/folders: the setup needs to have write
-   access either to the whole directory where iTop is installed or to the following
-   subdirectories (create them if needed)
-    - conf
-    - data
-    - env-production
-    - log
-
-3. Open the main iTop directory in your web browser. iTop should then display
-   the setup instructions on screen.
