My theme inherits from Blank. I know how to remove the footer links: Contact us, Advanced Search, etc... then I'd like to add a custom footer with 4 columns:
column 1 - Account links column 2 - general information links column 3 - Payment logo icons column 4 - Newsletter sign up form
All elements would be in a footer.phtml template, however I dont know how to add this phtml file to the footer area. And which folder this file should be located in? I know how to override templates, but the Blank theme does not have a footer.phtml enabled, so there is no a specific path to put my phtml file in.
