No README

If you run rpmlint over the RPMs produced for this project, one error is as follows:

gstlal-calibration.x86_64: W: no-documentation
The package contains no documentation (README, doc, etc). You have to include
documentation files.

which points to the fact that this project doesn't have a readme at all, never mind one that is linked to the RPMs.

Can a README.md be added that (briefly) describes the project?
