Display options using Redux Framework

I am using the Redux Framework (http://reduxframework.com/). I've copied the sample directory, renamed it and called it in functions.php. I see the redux framework inside wp-admin, however I unsure how to code options so they display (for example I don't know how to call them in index.php, footer.php

Could you advise how to display this array?

array(
'id'=>'footer-text',
'type' => 'editor',
'title' => __('Footer Text', 'redux-framework-demo'),
'default' => 'Powered by [wp-url]. Built on the [theme-url].',
),
