 ## Overview
-NVIDIA Kaolin library provides a PyTorch API for working with a variety of 3D representations and includes a growing collection of GPU-optimized operations such as modular differentiable rendering, fast conversions between representations, data loading, 3D checkpoints, differentiable camera API, differentiable lighting with spherical harmonics and spherical gaussians, powerful quadtree acceleration structure called Structured Point Clouds, interactive 3D visualizer for jupyter notebooks, convenient batched mesh container and more. Visit the [Kaolin Library Documentation](https://kaolin.readthedocs.io/en/latest/) to get started!

-Note that Kaolin library is part of the larger [NVIDIA Kaolin effort](https://developer.nvidia.com/kaolin) for 3D deep learning.
+Kaolin library is part of a larger suite of tools for 3D deep learning research. For example, the [Omniverse Kaolin App](https://docs.omniverse.nvidia.com/app_kaolin/app_kaolin/overview.html) allows interactive visualization of 3D checkpoints.

-## About the Latest Release (0.14.0)
+Visit the [Kaolin Library Documentation](https://kaolin.readthedocs.io/en/latest/) to get started!
 
-In this version we added a [conversion Op for mesh to SPC](https://kaolin.readthedocs.io/en/latest/modules/kaolin.ops.conversions.html#kaolin.ops.conversions.unbatched_mesh_to_spc),
-which allows turning meshes into Structured Point Cloud, our octree based representation.
-In addition, [interactive 3D visualizers](https://kaolin.readthedocs.io/en/latest/modules/kaolin.visualize.html) for Jupyter notebooks
-and a [SurfaceMesh class](https://kaolin.readthedocs.io/en/latest/modules/kaolin.rep.surface_mesh.html#kaolin-rep-surfacemesh) (see tutorials below).
+## About the Latest Release (0.13.0)
 
+With the version 0.13.0 we have added new [lighting features](https://kaolin.readthedocs.io/en/latest/modules/kaolin.render.lighting.html), most notably spherical gaussian [diffuse](https://kaolin.readthedocs.io/en/latest/modules/kaolin.render.lighting.html#kaolin.render.lighting.sg_diffuse_fitted) and [specular](https://kaolin.readthedocs.io/en/latest/modules/kaolin.render.lighting.html#kaolin.render.lighting.sg_warp_specular_term) reflectance, we also improved the spherical harmonics API and coefficients.
