Having Trouble Understanding Docs

[DommDynamite]

Hello, I am new to the diyHue project so forgive my ignorance here. But I have diyHue setup and working for my existing hue lights. I am now trying to configure my 2 feit RGB Tunable white bulbs to be connected to diyHue. I have checked the ESPHome section of the adding lights and I can even see that a feit bulb is used as an example. Unfortunately I cannot find the prerequisite information on how to actually apply any of the information on that page. The page details the information to be included in the config file but nowhere on where to put it. I'm also not sure where to get the information required for my bulb.

Can someone point out to me where this is documented?
