+LightGBM, Light Gradient Boosting
+==========
+
+
+
+
+LightGBM is a gradient boosting framework that using histogram based tree learning algorithm. It can outperform existing boosting tools on both learning speed and accuracy. Our [experiments](https://github.com/Microsoft/LightGBM/wiki/Experiments#comparison-experiment) shows it is about 6x faster than xgboost with much better prediction accuracy.
+
+LightGBM can be run on multiple machines, Our [experiments](https://github.com/Microsoft/LightGBM/wiki/Experiments#parallel-experiment) shows it can perform linear speed up in parallel learning.

+Binary Classification Example
+=====================
+Here is an example for LightGBM to run binary classification task.
+
+***You should copy executable file to this folder first.***
+
+#### Training
+
+For windows, by running following command in this folder:
+```
+LightGBM.exe config=train.conf
+```
+
+
+For linux, by running following command in this folder:
+```
+./LightGBM config=train.conf
+```
+
+#### Prediction
+
+You should finish training first.
+
+For windows, by running following command in this folder:
+```
+LightGBM.exe config=predict.conf
+```
+
+For linux, by running following command in this folder:
+```
+./LightGBM config=predict.conf
+```
