Add a code in category page

Well, I found the code in this page and I changed generate_after_entry_header with this:

add_action( 'generate_after_main_content', function() {
    if ( is_category() ) {
        echo 'what you want';
    }
} );

And “what you want” it only appears in category page -:)
Great, and thanks to more, I solved it again with your work -:)
