Help text for functionalities

You can't infer the use from the sole name of a lot of functionalities. We need help text to guide users through what is a functionality meant for. Example, this week I had to ask what was 'services' referring to when opening a meeting. A lot is not obvious, so it'd be nice if functionalities could be accompanied by help text that can be either prompted from a tooltip when hovering over a (?) button or plainly written there in smaller and lighter print. This project could very much be iterative and start via the manual and grow it's way into the code.
