I want to customize the checkout template and first want to try the supplied template and alter it via twig and use/block commands instead of copying/altering the whole template.
I'm looking at the template here: https://github.com/FoxyCart/2.0-templates/blob/master/checkout.inc.twig
I'm not entirely sure how to display the main checkout structure and then for example overwrite the current sidebar block.
I understand the blocks documentation, but the block_a and block_b examples don't include a parent/wrapper like checkout has.
Or should I extend the checkout block and then overwrite the sidebar block and then output the complete block?
PS > I'm a twig noob btw, so bare with me. I'm still going through the docs at sensio...
