Show tips about CLI arguments when used for the first time

[cernymatej]

I'm wondering if it would be a good idea to show tips about CLI arguments when the user selects an option for the first time. Something like:

✔ Initialize git repository?
No

-----------------------------------------------------------
TIP: You can use `--git-init=0` to skip git initialization.
-----------------------------------------------------------

(of course it should appear only for the first time and be styled nicely)
