As you can see, we used these as individual doors so installation hardware was not an issue. We used self-closing hinges and changed knob to polished nickel. 
As others have said, you can’t paint these with latex paint. We tried latex with a primer in it and it bubbled up immediately so we wiped it off. Color is not terrible so we may just leave them as is. Other than that, we are pleased as we think they look pretty sharp.
