README: rework the title hierarchy

In Markdown, a line underlining another one with '=' characters
represents a first level title, while a line underlining another one
with '-' characters represents a second level title.

Rework the title levels to gain visibility on the different sections and
to allow to split "Getting started" more easily (see my next commit for
additions to this section).
