To start with, you need couple of decent carpenters to build one correctly. A lot of strong wood, heavy weights to act as counter balance and something heavy to lob at the enemy. Then you need brave people to work the machine. Trebuchets were very dangerous to operate.
Oh and you also need someone who understands how the correct balance on the trebuchet is crucial. If you don't have the swing arm set up perfectly, the trebuchet could collapse or swing wildly and kill the people on the ground. They are a bit tricky.
The links below should give you an idea of how to construct one.

They are made of trees cut nearby to where they needed the trebuchet.
Potential energy in a trebuchet is converted into kinetic energy when the counterweight is released, causing the projectile to accelerate and be launched. The potential energy stored in the raised counterweight is what provides the force needed to throw the projectile.
Trebuchet is catapult that uses weight to fire.
Trebuchet MS was created in 1996.

the trebuchet was believed to have started in china around 300 bc
The trebuchet was much like a catapult. It was replaced with the cannon, and later, firearms.
A trebuchet uses the force of gravity to propel its projectile. The counterweight falling creates kinetic energy, which is transferred to the arm of the trebuchet and then to the projectile, launching it forward. Additionally, the leverage provided by the long arm of the trebuchet amplifies this force.
As far as i know there are three: the basic catapult, trebuchet, and the floating arm trebuchet.
A trebuchet is defined as a machine used in medieval siege warfare for hurling large stones or other missiles. The first trebuchet was invented by the Chinese in the 4th century BC.
