pathfinder/resources/shaders/README.md

This directory contains postprocessed versions of the shaders in the top-level shaders/ directory, for convenience. Don't modify the shaders here; instead modify the corresponding shaders in shaders/ and rerun make in that directory.

You will need glslangValidator and spirv-cross installed to execute the Makefile. On macOS, you can get these with brew install glslang spirv-cross.
