$ cd build && make install (or sudo make install)
$ darktable

optionally, to build the user manual:

 - Java JDK, gnome-doc-utils, Saxon 6.5.x, FOP and ImageMagick

then, type:
$ cd build
$ make darktable-usermanual

darktable has OpenCL support for graphics cards with:

 - > 1GB graphics RAM (more is better)

   drivers support all of the features that darktable needs)

enjoy!
