+Chainer is a powerful, flexible and intuitive deep learning framework.
+* Chainer supports CUDA computation. It only requires a few lines of code to
+  leverage a GPU. It also runs on multiple GPUs with little effort.
+* Chainer supports various network architectures including feed-forward nets,
+  convnets, recurrent nets and recursive nets. It also supports per-batch
+  architectures.
+* Forward computation can include any control flow statements of Python without
+  lacking the ability of backpropagation. It makes code intuitive and easy to
+  debug.
