It was a bit intimidating, but we assembled the gazebo ourselves without too many issues.  There one was piece of wood that we re-drilled holes in and we were either short one bolt or it was just misplaced.  I would only warn against adding wood sealant over the part numbers.  We did that, and it dried very dark, and then we couldn't see them.  The instructions gave clear measurements and indicated the placement of holes, so we were able to correctly locate each piece that way.  Overall a great project and it will add much needed shade.
