+## Introduction
+
+Caffe aims to provide computer vision scientists with a **clean, modifiable
+implementation** of state-of-the-art deep learning algorithms. Network structure
+is easily specified in separate config files, with no mess of hard-coded
+parameters in the code. Python and Matlab wrappers are provided.
+
+At the same time, Caffe fits industry needs, with blazing fast C++/Cuda code for
+GPU computation. Caffe is currently the fastest GPU CNN implementation publicly
+available, and is able to process more than **20 million images per day** on a
+single Tesla K20 machine \*.
+
+Caffe also provides **seamless switching between CPU and GPU**, which allows one
+to train models with fast GPUs and then deploy them on non-GPU clusters with one
+line of code: `Caffe::set_mode(Caffe::CPU)`.
+
+Even in CPU mode, computing predictions on an image takes only 20 ms when images
+are processed in batch mode.
