It is common, and useful, to have a section in install near the top which says something like:

--

If you don't read instructions
If you don't read instructions then do

./configure
bash third_party/build_all.bash
scons

Python scripts to run simulations, etc are in macros

--

I would say that if we can't write down how to install this in two/three lines, then the installation procedure is not as good as it should be.
