 1. Install [SPIRV-Tools](https://github.com/KhronosGroup/SPIRV-Tools#downloads) and add it to your PATH (for now, eventually we will automatically build and link it instead of calling executables)
 
-1. Next, look at the [examples](examples) folder. There are two projects here: [examples/example-shader](examples/example-shader) and [examples/example-runner](examples/example-runner). The example-shader project is a "GPU crate", one that will be compiled to a spir-v module. The example-runner project is a normal, CPU crate that uses vulkan to consume the example-shader spir-v module to display a "hello world" triangle.

     Run the example:
 
     ```shell
     cargo run --bin example-runner
     ```
 
-    This will build `rustc_codegen_spirv`, the compiler, then use that compiler to build `example-shader` into a SPIR-V module, then finally, build a vulkan sample app (taken from [ash's examples](https://github.com/MaikKlein/ash/blob/master/examples/src/bin/triangle.rs)) using the built SPIR-V module to display a triangle in a window.

     All of this is orchestrated by the [spirv-builder](spirv-builder) crate, which is used in example-runner's `build.rs` file. Please look at that file, as well as both example projects in general, to see how to set up your own shaders!
