Custom shaders getting started?

[lukors]

I'm trying to get started with custom shaders in Bevy. I've looked around in the bevy book, the cookbook, these discussions and Internet search, but failed to find anything other than the examples. Unfortunately the example I'm looking at isn't documented: https://github.com/bevyengine/bevy/blob/v0.6.1/examples/shader/shader_material.rs .

Can anyone point me to a resource for getting your first custom shader up and running in Bevy?
