Instructions were poorly written.  Diagrams were even worse.  The track looks really nice.  Just a side note that the lights actually have a right way and a wrong way to be put into the H track-be sure to put it in correctly or they won’t light.  ( would have been helpful for that to be mentioned in instructions).   I bought 2 more tracks today as I now know what mistakes not to make, and it should be much easier to install the next 2.
