-## Architecture
-Show below, there are three sets of APIs for different models.
-- `update_all`, `proppagate` are more global
-- `update_by_edge`, `update_to` and `update_from` give finer control when updates are applied to a path, or a group of nodes
-- `sendto` and `recvfrom` are the bottom primitives that update a message and node.
 
-![Screenshot](graph-api.png)
-
-## For Model developers
-- Always choose the API at the *highest* possible level.
-- Refer to the [GCN example](examples/pytorch/gcn/gcn_batch.py) to see how to register message and node update functions;

-## How to build (the `cpp` branch)
-
-Before building, make sure that the submodules are cloned.  If you haven't initialized the submodules, run
-
-```sh
-$ git submodule init
-```
-
-To sync the submodules, run
-
-```sh
-$ git submodule update
-```
-
-### Linux
-
-At the root directory of the repo:
-
-```sh
-$ mkdir build
-$ cd build
-$ cmake ..
-$ make
-$ export DGL_LIBRARY_PATH=$PWD
-```
-
-The `DGL_LIBRARY_PATH` environment variable should point to the library `libdgl.so` built by CMake.
-
-### Windows/MinGW (Experimental)
-
-Make sure you have the following installed:
-
-* CMake
-* MinGW/GCC (G++)
-* MinGW/Make
-
-You can grab them from Anaconda.
-
-In the command line prompt, run:
-
-```
-> md build
-> cd build
-> cmake -DCMAKE_CXX_FLAGS="-DDMLC_LOG_STACK_TRACE=0 -DTVM_EXPORTS" .. -G "MinGW Makefiles"
-> mingw32-make
-> set DGL_LIBRARY_PATH=%CD%
-```
