 In part this is because it's a niche language for a niche market, and in part this has been because the industry as a whole has sunk quite a lot of time and effort into the status quo. While over-all better alternatives to both languages exist, none of them are in a place to replace HLSL or GLSL. Either because they are vendor locked, or because they don't support the traditional graphics pipeline. Examples of this include CUDA and OpenCL. And while attempts have been made to create language in this space, none of them have gained any notable traction in the gamedev community.
 
-Our hope with this project is that we push the industry forward by bringing an existing, low-level, safe, and high performance language to the GPU; namely Rust. And with it come some additional benefits that can't be overlooked: a package/module system that's one of the industry's best, built in safety against race-conditions or out of bounds memory access, a wide range of tools and utilities to improve programmer workflows, and many others!

 ### Why Embark?
 
-At Embark, we've been building our in-house engine from the ground up in Rust. We have previous in-house experience developing [RLSL](https://github.com/MaikKlein/rlsl) (a first prototype of this idea) and we have some of the world's best rendering engineers that are familiar with the problems in current shading languages. So, we're in a unique place to solve this problem. We want to streamline our own internal development, facilitate code-sharing between GPU and CPU, but most importantly: to enable our users to very rapidly build great looking experiences.

We have previous experience in-house developing the [RLSL](https://github.com/MaikKlein/rlsl) prototype, and we have a team of excellent rendering engineers that are familiar with the problems in current shading languages both from games, game engines and other industries. So, we believe we are uniquely positioned to attempt solving this problem. 
 
-If we do this project right, one wouldn't necessarily need a team of rendering engineers to build a good looking game, instead one would simply use a few of the existing open-source crates that provide the graphical effects needed to create the experience you're after. Instead of sharing snippets of TAA code on forum posts, one could simply add the right crate(s).

 ## Project scope
 
-This project will involve a few things if we want to get the experience right, and it's quite broad. Initial stages will involve mostly just setting up the backend, however the project will be broader then that.
+The scope of this overall project is quite broad, but is in multiple stages
 
-- Currently only [SPIR-V](https://en.wikipedia.org/wiki/Standard_Portable_Intermediate_Representation) support is planned (the open compiler target for [Vulkan](https://en.wikipedia.org/wiki/Vulkan_(API)) but it's not unlikely that in future versions this will / should support [DXIL](https://github.com/microsoft/DirectXShaderCompiler/blob/master/docs/DXIL.rst) (the target for DirectX) or [WGSL](https://github.com/gpuweb/gpuweb/tree/main/wgsl) (the WebGPU shading language that's bijective with SPIR-V)
-- The first and primary target will be Vulkan shaders (vertex, fragment, etc.). However, Vulkan compute (what SPIR-V calls GLCompute) is also on the roadmap, as well as OpenCL compute (what SPIR-V calls Kernel).
-- Implement a `rustc` compiler backend, plugging in via `-Z codegen-backend`. This is the same mechanism that [rustc_codegen_cranelift](https://github.com/bjorn3/rustc_codegen_cranelift) and [rustc_codegen_gcc](https://github.com/antoyo/rustc_codegen_gcc) use.
-- [crates.io](https://crates.io) support to be able to publish SPIR-V crates
-- An Embark-provided rendering / framegraph abstraction to take advantage of this and to make it easy for users to re-use rendering effects.

+  - Currently only [SPIR-V] support is planned, [Vulkan](https://en.wikipedia.org/wiki/Vulkan_(API))'s open compiler target
+  - Possible a future version could suppport [DXIL](https://github.com/microsoft/DirectXShaderCompiler/blob/master/docs/DXIL.rst) (the target for DirectX) or [WGSL](https://github.com/gpuweb/gpuweb/tree/main/wgsl) (the WebGPU shading language that's bijective with SPIR-V)
+- Focus on Vulkan graphics shaders first, then after Vulkan compute shaders
+- [Cargo](https://github.com/rust-lang/cargo/) and [crates.io](https://crates.io) support to develop and publish SPIR-V crates
+- High-level render graph to take advantage of this, make it easy for users to develop and use rendering effects.
