This version does NOT use any image files (this avoids unnecessary traffic), adapts optically to the respective used style (via CSS @ definitions), is purely based on templates and supports German as well as English.
The editing of the footer content is not as convenient as with a plugin in the ACP, but easy to do directly in the template - the HTML guide contained here in the attached file is written in great detail and therefore suitable for beginners.
Unpack the downloaded ZIP file with a Pack program (eg with the free program 7-Zip), open the included HTML manual with your browser and read carefully.
Each step in the tutorial can be marked as done by a included color marker.
