Hello @Zens , adding a new block to the footer section would require some basic knowledge of HTML and a bit of CSS.
You would need to edit the footer.liquid section and add the HTML block exactly where you want it to be positioned in the page. You can inspect the source code of your footer to determine where that would be in some instances.
Also, you might need to add some CSS styles like padding, margin, display, e.t.c to make it really fit in to the footer and not like it was just dropped on it.
