 - All the module interface are listed in [include](../../include), these interfaces are heavily documented.
 - You read the [Doxygen Version](https://mxnet.readthedocs.org/en/latest/doxygen) of the document.
 - Each module will only depend on other module by the header files in [include](../../include).
-- The implementation of module is in [src](../../src) folder. 
+- The implementation of module is in [src](../../src) folder.
 - Each source code only sees the file within its folder, [src/common](../../src/common) and [include](../../include).
 
 Most modules are mostly self-contained, with interface dependency on engine.

+Dependency Engine for Deep Learning
+===================================
 One always important theme of deep learning libraries is to run faster and scale to larger
 dataset. In order to do so, a natural direction is always go beyond using one device(GPU),
 and make uses of more computation resources.
