 Introduction
 ~~~~~~~~~~~~
 cuGraph is a library of graph algorithms that seamlessly integrates into the
 RAPIDS data science ecosystem and allows the data scientist to easily call
-graph algorithms using data stored in GPU DataFrames, NetworkX Graphs, or
-even CuPy or SciPy sparse Matrices.
+graph algorithms using data stored in GPU DataFrames, NetworkX Graphs, or even
+CuPy or SciPy sparse Matrices. Our major integration effort with NetworkX
+allows for **zero code change** GPU acceleration through the use of the
+nx-cugraph backend. NetworkX and the nx-cugraph backend offer a seamless
+transition to GPU accelerated graph analytics for NetworkX users with access to
+a supported GPU.
+
+Getting started with cuGraph
+
+Required hardware/software for cuGraph and `RAPIDS <https://docs.rapids.ai/user-guide>`_
+ * NVIDIA GPU, Volta architecture or later, with `compute capability <https://developer.nvidia.com/cuda-gpus> 7.0+`_
+ * CUDA 11.2-11.8, 12.0-12.5
+ * Python version 3.10, 3.11, or 3.12
+ * NetworkX version 3.0 or newer in order to use use the nx-cuGraph backend. NetworkX version 3.4 or newer is recommended. (`see below <#cugraph-using-networkx-code>`).
+
+Installation
+The latest RAPIDS System Requirements documentation is located `here <https://docs.rapids.ai/install#system-req>`_.
+
+This includes several ways to set up cuGraph
+
+* From Unix
+
+  * `Conda <https://docs.rapids.ai/install/#conda>`_
+  * `Docker <https://docs.rapids.ai/install/#docker>`_
+  * `pip <https://docs.rapids.ai/install/#pip>`_
+
+
+**Note: Windows use of RAPIDS depends on prior installation of** `WSL2 <https://learn.microsoft.com/en-us/windows/wsl/install>`_.
+
+* From Windows
 
-Note: We are redoing all of our documents, please be patient as we update
-the docs and links
+  * `Conda <https://docs.rapids.ai/install#wsl-conda>`_
+  * `Docker <https://docs.rapids.ai/install#wsl-docker>`_
+  * `pip <https://docs.rapids.ai/install#wsl-pip>`_

+cuGraph Using NetworkX Code
+
+cuGraph is now available as a NetworkX backend using `nx-cugraph <https://rapids.ai/nx-cugraph/>`_.
+nx-cugraph offers NetworkX users a **zero code change** option to accelerate
+their existing NetworkX code using an NVIDIA GPU and cuGraph.
+
+
+ Cugraph API Example
+
+ .. code-block:: python
+
+  import cugraph
+  import cudf
+
+  # Create an instance of the popular Zachary Karate Club graph
+  from cugraph.datasets import karate
+  G = karate.get_graph()
+
+  # Call cugraph.degree_centrality
+  vertex_bc = cugraph.degree_centrality(G)
+
+There are several resources containing cuGraph examples, `the cuGraph notebook repository <https://github.com/rapidsai/cugraph/blob/main/notebooks/README.md>`_
+has many examples of loading graph data and running algorithms in Jupyter notebooks.
+The `cuGraph test code <https://github.com/rapidsai/cugraph/tree/main/python/cugraph/cugraph/tests>_` contain python scripts setting up and calling cuGraph algorithms.
+A simple example of `testing the degree centrality algorithm <https://github.com/rapidsai/cugraph/blob/main/python/cugraph/cugraph/tests/centrality/test_degree_centrality.py>`_
+is a good place to start. Some of these show `multi-GPU tests/examples <https://github.com/rapidsai/cugraph/blob/main/python/cugraph/cugraph/tests/centrality/test_degree_centrality_mg.py>`_ with larger data sets as well.
