Removing "Powered by WordPress"

Does anyone know what part of this i need to remove in order to get rid of the “Powered by Wordpres” and “Designed by Theme Alley”?

<div class="site-info">
              <?php if( of_get_option('footer_logo_image') ) : ?>
				<div class="footer-logo">
                	<img src="<?php echo of_get_option('footer_logo_image'); ?>">
                </div>
				<?php else : ?>
                <h3><a href="<?php echo esc_url( home_url( '/' ) ); ?>"><?php bloginfo('name'); ?></a></h3>
                <?php endif; ?>
                <?php get_template_part( 'footer', 'copyright' ); ?>
                <?php if( !of_get_option('show_footer_credits') || of_get_option('show_footer_credits') == 'true' ) : ?>
                <?php if( is_home() || is_front_page() ): ?>
                <p><?php printf( __( 'Designed by: %1$s.', 'themealley_business' ), '<a href="https://www.themealley.com/" rel="designer">ThemeAlley.com</a>' ); ?></p>
                <?php endif; ?>

                <?php endif; ?>
                <?php if( !of_get_option('show_footer_search') || of_get_option('show_footer_search') == 'true' ) : ?>
                <div class="footer-search"><?php get_search_form(); ?></div>
				<?php endif; ?>
