That's a good idea, and I forgot about TLDR in README. I added there too.

About marking optional: I thought about it for a bit. There is currently a `meson install` command in both docs, which is also optional and not everyone needs it.
Peter, do you think we should mark both as optional?

I have the thought of, maybe people would understand that if they just need to compile than they just run compile, and if they need tests they run tests?
