florbv, I haven’t work with child themes, so I wouldn’t know what’s the right way to go. You can check wordpress documentation.

As for the customized files, I was talking about Woocommerce, which is common to have it updated once in a while. Regarding this shipping plugin, we’re actually hacking it, so we have to overwrite the shipping-awd.php and NEVER update it.

florbv, you can put your code in github.
By the way, adding the states (or any othe customization) inside the plugin folder is not recommended, as it may get lost whan you upgrade the plugin.
You can add the states in your theme functions.php like this:

add_filter( 'woocommerce_states', 'custom_woocommerce_states' );
function custom_woocommerce_states( $states )
{
	$states['PH'] = array(
		'XXX' => 'Xxxxx',
		...
	);
	return $states;
}

Hi,

all changes should be made in the plugin file: shipping-awd.php
