......@@ -7,6 +7,10 @@ All instructions below are aimed to compile 64-bit version of LightGBM.
It is worth to compile 32-bit version only in very rare special cases of environmental limitations.
32-bit version is slow and untested, so use it on your own risk and don't forget to adjust some commands in this guide.
Users who want to perform benchmarking can make LightGBM output time costs for different internal routines via adding ``-DUSE_TIMETAG=ON`` to CMake flags.
It is possible to build LightGBM in a debug mode. In this mode all compiler optimizations are disabled and LightGBM performs more checks internally. To enable debug mode you can add ``-DUSE_DEBUG=ON`` to CMake flags or choose ``Debug_*`` configuration (e.g. ``Debug_DLL``, ``Debug_mpi``) in Visual Studio depending on how you are building LightGBM.
For the build of Python-package and R-package, please refer to `Python-package`_ and `R-package`_ folders respectively.
Also you can download artifacts of the latest successful build in master branch (nightly builds): |download artifacts|.
