-### `bgfx_compile_shader_to_header`
+### `bgfx_compile_shaders`
 Add a build rule for a `*.sc` shader to the generated build system using shaderc.
 ```cmake
-bgfx_compile_shader_to_header(
+bgfx_compile_shaders(
 	TYPE VERTEX|FRAGMENT|COMPUTE
 	SHADERS filenames
 	VARYING_DEF filename
 	OUTPUT_DIR directory
+	[AS_HEADER]
 )
 ```
-This defines a shaderc command to generate headers for a number of `TYPE` shaders with `SHADERS` files and `VARYING_DEF` file in the `OUTPUT_DIR` directory. There will be one generated shader for each supported rendering API on this current platform according to the `BGFX_EMBEDDED_SHADER` macro in `bgfx/embedded_shader.h`.
+This defines a shaderc command to generate binaries or headers for a number of `TYPE` shaders with `SHADERS` files and `VARYING_DEF` file in the `OUTPUT_DIR` directory. There will be one generated shader for each supported rendering API on this current platform according to the `BGFX_EMBEDDED_SHADER` macro in `bgfx/embedded_shader.h` for headers and in the directory expected by `load_shader` in `bgfx_utils.h`.
 
-The generated headers will have names in the format of `${SHADERS}.${RENDERING_API}.bin.h` where `RENDERING_API` can be `glsl`, `essl`, `spv`, `dx9`, `dx11` and `mtl` depending on the availability of the platform.
+The generated headers will have names in the format of `${RENDERING_API}/${SHADERS}.bin[.h]` where `RENDERING_API` can be `glsl`, `essl`, `spv`, `dx11` and `mtl` depending on the availability of the platform.
 
 Adding these `SHADERS` as source files to a target will run `shaderc` at build time and they will rebuild if either the contents of the `SHADERS` or the `VARYING_DEF` change.
