First, it came with no instructions, but if you count the bolts, you can figure out what goes where.Second, the bolts to attach it to the dock were not included. We had to come up with our own to attach it.Third, one bolt didn't fit. It was as if someone drilled the hole in the wrong spot. We had to come up with a thinner bolt to make it fit.Fourth, we had to put it in a more shallow part of the dock than we really wanted to because the legs only extend by 10-12 inches. We probably could have engineered something to extend the legs further or come up with something new, but we decided to put it in the less than ideal place, for now. However, the ladder seems so sturdy and is so easy to use when getting in and out of the water, it's worth the trip to the hardware store or the extra problem solving to install it.
