How do I change the footer text?

Hey, I’d like to change the text in the footer to something else. I’d like for it to say something like copyright “my business” and maybe the adress or contact info. I’m using this theme: https://wpexplorer.me/demo.php?theme=ultra

Where do I change it? Here are excerpts from the footer.php and css…

Footer

<?php
global $options;
foreach ($options as $value) {
if (get_option( $value['id'] ) === FALSE) { $$value['id'] = $value['std']; } else { $$value['id'] = get_option( $value['id'] ); }
}
?>
<div class="clear"></div>
</div><!-- /container -->
</div><!-- /wrap -->
<div id="copyright">
&copy; <?php the_time('Y') ?> <?php bloginfo('name'); ?>
	<?php if ($xs_disable_social_links == "true") { ?>
	<?php } else { ?>
		<ul id="social">
			<li><a href="https://www.twitter.com/<?php echo $xs_twitter ?>" title="Twitter"><img src="<?php bloginfo('template_url'); ?>/images/twitter.png" alt="Twitter" /></a></li>
			<li><a href="<?php echo $xs_facebook ?>" title="Facebook Page"><img src="<?php bloginfo('template_url'); ?>/images/facebook.png" alt="Facebook" /></a></li>
			<li><a href="<?php echo $xs_feed ?>" title="Feed"><img src="<?php bloginfo('template_url'); ?>/images/feed.png" alt="Feed" /></a></li>
	</ul><!-- /social -->
	<?php } ?>
</div><!-- /copyright -->
<?php wp_footer(); ?>
</body>
</html>
