We did not install this fixture, so cannot comment on instructions and assembly, as our contractor did all the work! We are extremely pleased with how it looks, moves, etc. It was well worth the money, the customer service has been good, and we would definitely recommend this, or larger of same, to anyone (we installed over sink). I wish we had paid more attention to measuring our space before ordering; a five-light fixture would have looked better! Measure before you order. Classy light!
