Deep Graph Library (DGL) is a Python package built for easy implementation of
graph neural network model family, on top of existing DL frameworks (currently
supporting PyTorch, MXNet and TensorFlow). It offers a versatile control of message passing,
speed optimization via auto-batching and highly tuned sparse matrix kernels,
and multi-GPU/CPU training to scale to graphs of hundreds of millions of
nodes and edges.

Getting Started
---------------

For absolute beginners, start with the :doc:`Blitz Introduction to DGL <tutorials/blitz/index>`.
It covers the basic concepts of common graph machine learning tasks and a step-by-step
on building Graph Neural Networks (GNNs) to solve them.

For acquainted users who wish to learn more advanced usage,

* `Learn DGL by examples <https://github.com/dmlc/dgl/tree/master/examples>`_.
* Read the :doc:`User Guide<guide/index>` (:doc:`中文版链接<guide_cn/index>`), which explains the concepts
  and usage of DGL in much more details.
* Go through the tutorials for :doc:`Stochastic Training of GNNs <tutorials/large/index>`,
  which covers the basic steps for training GNNs on large graphs in mini-batches.
* :doc:`Study classical papers <tutorials/models/index>` on graph machine learning alongside DGL.
* Search for the usage of a specific API in the :doc:`API reference manual <api/python/index>`,
  which organizes all DGL APIs by their namespace.
