Relates to #184, #137, #104, #91, #90, #89, #27.
README.md is outdated.
The main doc browseable from Vim is also outdated.
The outdated README.md should be overhauled, plus along with some other fixes. We can preserve the flexibility of setup and plugin choice, while recommending a 'quick start' example for having it working correctly from day 0.
