Instructions are easy to follow.  Be sure to leave all the screws somewhat loose until the table had been leveled--in our enthusiasm we tightened some too much and had to repeat the leveling process.  Then tighten all 16 screws!  I'm not certain the finish is adequate to protect the table from spills; we decided we didn't want it to grey naturally and don't want to put a cover on it (it's too pretty).  We've purchased outdoor urithane and plan to apply it in multiple coats to protect from spills, UV rays and mold/mildew in our moist NW Pacific environment.  It's maintained with a light sanding and one coat every three years.  (There are oil-based products that are easier to apply but they're tinted and have to be applied annually.)  We really like the price, size, shape, design, and color of the table and are happy with the purchase.
