Adam S. Smith@pfefferle So, I created the parts folder containing the html file as suggested. There's still no Templates Parts menu option immediately under Appearance, but if I go to Patterns, there are now options 'All Template Parts' and 'General'. This matches the screenshot in the instructions, but differs to the text in your instructions. Instruction say Appearance > Editor > Template Parts; but (for me at least) it is Appearance > Patterns).
