How to change the footer text

I have footer.php file as below in my child theme, but I don’t know which specific line I should to add or replace it.

Thanks for your support

<?php

/**

* Footer Section for our theme.

*

* @package ThemeGrill

* @subpackage Ample

* @since Ample 0.1

*/

?>

</div><!– .main-wrapper –>

<footer id=”colophon”>

<div class=”inner-wrap”>

<?php get_sidebar( ‘footer’ ); ?>

<div class=”footer-bottom clearfix”>

<div class=”copyright-info”>

<?php do_action( ‘ample_footer_copyright’ ); ?>

</div>

<div class=”footer-nav”>

<?php

if ( has_nav_menu( ‘footer’ ) ) {

wp_nav_menu( array( ‘theme_location’ => ‘footer’, ‘depth’ => -1 ) );

}

?>

</div>

</div>

</div>

</footer>

<i class=”fa fa-angle-up”></i>

</div><!– #page –>

<?php wp_footer(); ?>

</body>

</html>

It worked now.
Thank you!

Thanks again
