 # About ALab
-The ALab data set is the Animal Logic interpretation and implementation of real-world production and pipeline concepts in USD.
+Originally released in 2021 by Animal Logic, the ALab data set is the Netflix Animation Studios interpretation and implementation of real-world production and pipeline concepts in USD.
 
 It includes over 300 fully surfaced assets derived from an internally produced project, rather than created from scratch as a "USD reference implementation." It consequently exhibits the complexities (and some of the messiness) of real production assets. If one were to build a USD structure for the sole purpose of showcasing USD, it would lead to a different result.
 
-The `entry.usda` `stage` places you in a shot with a structure similar to how we use it at Animal Logic. Since no shot is complete without animation, included are two animated characters, each with some level of proceduralism. Due to this proceduralism requiring some custom `schemas` for our internal Glimpse renderer, we have provided a hint on what these procedurals create in a separate `baked_procedurals` package. This is the "cached" content that would be sent to the renderer per-frame.

 For “production style rendering” we also provide an additional package `texture_pack` with multi UDIM, mipmapped 4K OpenEXR textures.

+## Splat Pack (WIP)
+* This contains the ALab as a single gaussian splat in USD, using the new/upcoming [Lightfields USD schema](https://github.com/PixarAnimationStudios/OpenUSD/pull/3716). It is a WIP, but we wanted to get a test branch out for people to start iterating on and to help push forward collaboration on the schema and refining this DPEL asset. 
+
+Files currently in this pack:
+- The original .ply file
+- A .usdc file of the ALab Splat
+- A .usda file of transformations to make the splat match up with ALab (this is temporary)
+- The USD camera for the rendered images used to generate the splat
+
+In order to successfully view the usdc file you will need to have built usd with [this branch](https://github.com/PixarAnimationStudios/OpenUSD/pull/3716) for the schema and usdview renderer. 
+
+More details on how to test with this at the moment are [here in the docs](docs/src/pages/gaussianSplat.md)
