-Description: Tree based algorithms can be improved by introducing boosting frameworks. 'LightGBM' is one such framework, and this package offers an R interface to work with it.
+Description: Tree based algorithms can be improved by introducing boosting frameworks. 
+    'LightGBM' is one such framework, based on Ke, Guolin et al. (2017) <https://papers.nips.cc/paper/6907-lightgbm-a-highly-efficient-gradient-boosting-decision>.
+    This package offers an R interface to work with it.
     It is designed to be distributed and efficient with the following advantages:
         1. Faster training speed and higher efficiency.
         2. Lower memory usage.
