[Plugin: List category posts] Getting the shortcode to work if placed in theme ?

I want to have the short code render in part of index.php.

Does anyone know how to do this so it actually works? When I put the shortcode in the index php (even in a div), it just renders as the code – instead of the list of posts.

Thanks
