-Deep learning library for Apache Spark
+#BigDL
+
+A scalable deep learning library for Apache Spark.
+
+Here's the summary of core features:
+* a powerful N-dimensional array
+* lots of math and data manipulating operations
+* rich neural network layers
+* effecient distributed numeric optimization routines on Apache Spark
+* powered by MKL and MKL DNN, fast and optmized on Intel hardware platforms
+
+##How to build
+###Linux
+1. Download [Intel MKL](https://software.intel.com/en-us/intel-mkl) and install it in your linux box
+2. Prepare MKL build environment
source PATH_TO_MKL/bin/mklvars.sh <arch>
The **<arch>** can be *ia32*, *intel64*, or *mic*, which depends on your system.
+3. Build project
mvn clean package -DskipTests -P mkl
+
+##Example
+* MNIST example
+* Cifar10 example
+* Imagenet example
