Write the next sentence in this paragraph:

How to set up a trampoline
Check the packages.
All of the materials for a trampoline will usually come in two or three packages. Empty each of the packages and make sure that you have everything that is listed in the instructions.
A missing piece can prevent you from setting up the trampoline properly, so you don't want to begin putting it together without double checking that you have everything you need. If there is a missing piece, call the company you bought the trampoline from and see what can be done about it.
