[Theme: Olsen Light] Duplicating page.php for WooCommerce

I can’t fully activate WooCommerce with Olsen Light because WC’s content wrapper does not match the theme (according to them).

The instructions from WC’s documentation tell me to instead use their catch-all woocommerce_content() function inside the theme by duplicating Olsen Light’s theme page.php. There is a series of instructions after this, but I am hung up on actually duplicating the page.php file. I cannot find a source for duplicating.

I am fairly new to this. Suggestions?

Thanks,
Miranda
