How to install intel CPU on a Motherboard

Today I watched videos in preparation of assembling a computer.
In this video, he installs a CPU on the motherboard. First, he emphasized the importance of wearing a de-static device. Then, he removed the CPU and stated how it's important to only touch the CPU in the sides. After that, he secured the CPU in place. Finally, he installed the fan, noting how to push down firmly on the pegs on each corner.
