 This subdirectory contains Android's Vulkan loader, as well as some Vulkan-related tools useful to platform developers.
 
+## Documentation

 ## Coding Style
 
 We follow the [Chromium coding style](https://www.chromium.org/developers/coding-style) for naming and formatting, except with four-space indentation instead of two spaces. In general, any C++ features supported by the prebuilt platform toolchain are allowed.

 ## Code Generation
 
-We generate several parts of the loader and tools from a Vulkan API description file, stored in `api/vulkan.api`. Code generation must be done manually because the generator tools aren't part of the platform toolchain (yet?). Files named `foo_gen.*` are generated from the API file and a template file named `foo.tmpl`.

- To run the generator:

-### One-time setup
-- Install [golang](https://golang.org/), if you don't have it already.
-- Create a directory (e.g. `$HOME/lib/go`) for local go sources and binaries and add it to `$GOPATH`.
-- `$ git clone https://android.googlesource.com/platform/tools/gpu $GOPATH/src/android.googlesource.com/platform/tools/gpu`
-- `$ go get android.googlesource.com/platform/tools/gpu/api/...`
-- You should now have `$GOPATH/bin/apic`. You might want to add `$GOPATH/bin` to your `$PATH`.

-### Generating code
-To generate `libvulkan/*_gen.*`,
-- `$ cd libvulkan`
-- `$ apic template ../api/vulkan.api code-generator.tmpl`
-Similar for `nulldrv/null_driver_gen.*`.
+Install Python3 (if not already installed) and execute below:
+`$ ./scripts/code_generator.py`
