Shortcodes

Shortcode	Shows
`[siteryn_mini_cart]`	A cart icon button with its count; the Mini Cart dropdown opens under it (hover or click, as set). Several on one page are fine.
`[siteryn_side_cart]`	A cart button with its count that opens the Side Cart (the drawer itself is already on every page).

Neither takes attributes; they follow your settings. Each shows only while its cart is enabled (Enable Mini Cart / Enable Side Cart). In the block editor, add them with a Shortcode block, e.g. in your header template part. The settings screen's Shortcodes card has a Copy button for each.

In a theme template

<?php
if ( function_exists( 'siteryn_mcsc_mini_cart' ) ) {
	siteryn_mcsc_mini_cart(); // or siteryn_mcsc_side_cart();
}
?>

Both print the same output as the shortcodes.

Shortcode or Header Cart?

Your theme already has a cart icon: use Header Cart to connect it.
It doesn't, or you want a cart somewhere else: use a shortcode.

To change the markup itself, override the templates from your theme: see Templates.
