As a newcomer to this project, my first question is: do the libraries support my cameras.
I recommend that you have available at the main page at a high level a link to a table (in wiki?) of RAW formats that are supported &etc.
I have a Nikon D750 and 610, I should not have to spend more than a minute trying to determine if your libraries support these versions.
Actual camera list is
Actual camera list is returned by LibRaw::cameraList() call (http://www.libraw.org/docs/API-CXX-eng.html#cameraList )
There is no list on site, because the list updates frequently (if you use development branch), also actual list depends on actual version you use.
Nikon D610 is supported in LibRaw 0.16, D750 in 0.17(-Alpha1)
Also, to use LibRaw as library you definitely need to spend 'more than minute'.
