Most instructions are ready to be followed.  Watch the interior versus exterior positioning of the wood framed narrow panels. the angled edges will face inward for the glass doors to pass thru.  This is unstated and could be put in backwards.  Also, if the mirrors do not seem to fit as they should you can either release the pressure on them by loosening the end screws of the pieces they will fit between and the mirror should slip in , then carefully retighten to avoid mirror damage OR check to be sure you do not have the pieces grooved backward to have the mirrors lie in place easily.  To carefully pull this together, allow more than the 80 minutes noted in the paperwork. We worked on the pieces following the order noted in their directions and completed the bottom half, then came back later and did the same with the top half.  We did not give it 5 stars because we were short 14 of the small screws that hold the back panels that cover the mirrors.
