Basically, all you will need to do is mount the track on an overhead surface, and attach the fixtures. Depending on the model that you buy, there may be proprietary clips, adjusters, and other items that will need to be assembled. The best thing you can do is read the instructions carefully, and make sure that you understand each step in the process. If you do not understand something, or notice items missing, there should be a phone number where you can contact the manufacturer of your low voltage track lighting system.
