help on Phil Sturgeon's RESTful API

[eluser]ebot[/eluser]
I tried adding Phil Sturgeon RESTful api to my application by putting the rest.php in the config, folder, REST_controller.php in the application/library, and tried the example, but i got this error message: Your rest.php file does not appear to contain a valid configuration array., i will appreciate any help from you people on how to get it running well on codeigniter application,
thanks

You missed the rest.php config file. That config file lets you enable/disable HTTP authentication and change the name of the "Realm".

Sorry I missed this, you could have PMed me. ;-)
