Adding content to order confirmation emails.

Can anyone telling me which file to edit to add content to the order confirmation email sent to my customers?

I looked in email/ email_template_checkout.html added a few <p> with content and nothing changed in the email.

I know tpl_checkout_success_default is used for the confirmation page after and order but doesn't affect the email that goes out. I pretty much want them the same.

thanks

I managed to edit includes/languages/checkout_process.php.

i guess this could be closed

Thanks for the update that this is working and for posting the solution to help others ... :smile:
