Shaderlab, HLSL, How to add support?

[CapelaGames]

Hi,

I am new to this, I have been looking around but I could not find documentation on how to add my own LSP. (This might be due to me misunderstanding things)

I've been using Unity's shaderlab (which uses HLSL), and I would love to have HLSL support in nvim.

I did find this LSP on github https://github.com/shader-ls/shader-language-server .
But I couldn't work out how I could add it myself to mason.

I also did find #625 which mentions GLSL. I could create a request similar to that one for shaderlab and hlsl, but I thought I would ask first. It does mention "If the distribution of the package is simple, the installation will most likely be so as well. " But I don't know where to start.

Any help would be amazing, thank you.
