Creating first Aplication problem.. Fedora/Apache

I’m using linux Fedora 17

requirements.php : Your server configuration satisfies the minimum requirements by this application.

Using Apache server so yii is in var/www/html/yii

When i go localhost/yii i get folders tree.

Tried few commands to generate app but no off them works.:

php yii/framework/yiic webapp helloworld - how should it looks?

Could not open input file: yii/framework/yiic

I don’t need database i would like to benchmark text render so i need controller + view… that would put ‘Hello world!’

Sorry for my english and thanks for any help.
