Coraline: remove proudly powered by wordpress

I’m very new to WordPress and wish to remove the footer message: ‘proudly powered by WordPress’. Could someone tell me which part of the code to change/ remove please? Thanks!

<div id=”footer” role=”contentinfo”>
<?php get_sidebar( ‘footer’ ); ?>

<div id=”colophon”>
<?php printf( __( ‘Theme: %1$s by %2$s’ ), ‘Coraline’, ‘Automattic‘ ); ?> <span class=”generator-link”>” title=”<?php esc_attr_e( ‘A Semantic Personal Publishing Platform’, ‘coraline’ ); ?>” rel=”generator”><?php printf( __( ‘Proudly powered by %s.’, ‘coraline’ ), ‘WordPress’ ); ?></span>
