For mounting a chain with quick release, multi-grip pliers and possibly a flat screwdriver will suffice. If you need to shorten it then you will need a chain tool. To avoid this, remember to count the number of links necessary to order the correct length.

A chain is made up of different links, or links, and can be of different widths. It is essential to check the type of secondary transmission which you need before order. All the parts of the kit, namely the pinion, the chain and the crown, must imperatively be same type (not).
