Get ready for the worst instruction manual you have ever seen. Some of the numbers on the part list and the numbers they use later are different, so it’s extremely confusing. 
Also, the hole that they cut in the countertop for the vessels sink and sink drain assembly is too big, so the nut you are supposed to tighten underneath just passes freely up inside the hole to the point where tools will not fit, but the sink is still loose. 
I get it, the price is low, but you really can get a better vanity set for about the same price at your local hardware store.
