README: ToC + Notice telling users to read important sections

[molleweide]

Below the top section [Dorothy is a dotfile ecosystem featuring: ...] that highlights features
there should be one of those nice colorful banners with the message:

NOTE|IMPORTANT: 
Please read installation, prerequisites, and requisites sections before installing, so that you are aware of the minimal dependency set Dorothy will attempt to install upon installation.

And then a table of contents with links to each section.

This would increase the probability that users will actually read the sections and avoid most confussions as to why some packages are installed upon installation.

Nah, no way. We need to support YOLO users. We cannot and should not expect users to pass an exam before they try Dorothy; that shouldn't be needed.

We already have feedback from users that have studied the manual, that there was too much to keep in their head to be aware of how it all impacts them during their Dorothy experience, not before it. Experience is how abstract knowledge is made relevant, and without relevance it is forgotten; they need to experience the ledge to continue to know.

YOLO is largely personality driven (high openness, low neuroticism), some people like the act of learning the hard way, and enjoy the discovery from confusion, as it promotes self-verification and what they didn't need to self-verify probably wasn't important to them. Try and test it first, if it meets my goals, wicked, if it doesn't, now is the time for study.

The manual's extreme detail is more for the opposite personality (lower openness, higher neuroticism), those who need the manual before they engage in risk. The manual and then the alignment of the experience to the manual determines their trust; and this ongoing trust is the measurement of whether or not the project meets or can achieve their goals.

The solution for both types of users and also to #263 is a better first run experience, that explains what is happening and why. It's what #281 contributes to with the new setup-shell etc.
