Why are Services so vague in the Roblox Wiki

I’ve been searching in the Class Index for new scripts, events, and functions to learn when I realized that the Services have barely any context to what they do and how they even function. This is extremely off-putting to devs trying to learn new stuff like I am, and I’m extremely confused about what I should be learning on the Roblox Wiki.

Usually services with little to no info on them are used internally by Roblox. In other words, you’re not supposed to use them.

If you want to find services that are meant to be used, you can find some in the sidebar in the API reference.
