 ## What's new
 - We have recently released [ThunderGBM](https://github.com/Xtra-Computing/thundergbm), a fast GBDT and Random Forest library on GPUs.
-- add scikit-learn interface, see [here](https://github.com/zeyiwen/thundersvm/tree/master/python)
+- add scikit-learn interface, see [here](https://github.com/Xtra-Computing/thundersvm/tree/master/python)
 - pre-built binaries and DLL for Windows x64 on CPUs are [avaliable](https://ci.appveyor.com/project/shijiashuai/thundersvm/branch/master/artifacts)
 ## Overview
 The mission of ThunderSVM is to help users easily and efficiently apply SVMs to solve problems. ThunderSVM exploits GPUs and multi-core CPUs to achieve high efficiency. Key features of ThunderSVM are as follows.
 * Support all functionalities of LibSVM such as one-class SVMs, SVC, SVR and probabilistic SVMs.
 * Use same command line options as LibSVM.
-* Support Python, R and Matlab interfaces.
+* Support [Python](python/), [R](R/) and [Matlab](Matlab/) interfaces.
 * Supported Operating Systems: Linux, Windows and MacOS.
 
 **Why accelerate SVMs**: A [survey](https://www.kaggle.com/amberthomas/kaggle-2017-survey-results) conducted by Kaggle in 2017 shows that 26% of the data mining and machine learning practitioners are users of SVMs.
