+		**Setting FTP Preferences in a Config File**
 
--  **hostname** - the FTP hostname. Usually something like:
-   ftp.example.com
--  **username** - the FTP username.
--  **password** - the FTP password.
--  **port** - The port number. Set to 21 by default.
--  **debug** - TRUE/FALSE (boolean). Whether to enable debugging to
-   display error messages.
--  **passive** - TRUE/FALSE (boolean). Whether to use passive mode.
-   Passive is set automatically by default.
+		If you prefer you can store your FTP preferences in a config file.
+		Simply create a new file called the ftp.php, add the $config array in
+		that file. Then save the file at *application/config/ftp.php* and it
+		will be used automatically.
