The build guide and instructions are present in the box but absolutely terrible. There is no clear instructions on the ukulele where to position the fretboard, bridge etc. There aren't pre-drilled holes for screws which makes it incredibly difficult to screw in anything. The screwdriver is useless. There was not enough glue so I had to use super glue. You need professional workshop clamps for the fretboard to stick otherwise it warps. The strings are bundled together and it was never made clear that all four strings are actually of different diameter. They could have made them different colors or used colored tape to indicate but no. This is not something anyone can easily put together.
