+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+/**
+ * CallOrderStateMachineHelper is a helper class for setting up a compile-time
+ * checked state machine that a sequence of calls is correct for completely
+ * setting up the state for some other type.
+ *
+ * Two examples where this could be used are with setting up a "Builder" flow
+ * for initializing an instance of some type, and writing tests where the state
+ * machine sets up expectations and preconditions, calls the function under
+ * test, and then evaluations postconditions.
+ *
+ * The purpose of this helper is to offload some of the boilerplate code to
+ * simplify the actual state classes, and is also a place to document how to
+ * go about setting up the state classes.
+ *
+ * To work at compile time, the idea is that each state is a unique C++ type,
+ * and the valid transitions between states are given by member functions on
+ * those types, with those functions returning a simple value type expressing
+ * the new state to use. Illegal state transitions become a compile error because
+ * a named member function does not exist.
+ *
+ * Example usage in a test:
+ *
+ *    A two step (+ terminator step) setup process can defined using:
+ *
+ *        class Step1 : public CallOrderStateMachineHelper<TestFixtureType, Step1> {
+ *           [[nodiscard]] auto firstMockCalledWith(int value1) {
+ *              // Set up an expectation or initial state using the fixture
+ *              EXPECT_CALL(getInstance->firstMock, FirstCall(value1));
+ *              return nextState<Step2>();
+ *           }
+ *        };
+ *

+ *
+ *    Note how the non-terminator steps return by value and use [[nodiscard]] to
+ *    enforce the setup flow. Only the terminator step returns void.
+ *
+ *    This can then be used in the tests with:
+ *
+ *        Step1::make(this).firstMockCalledWith(value1)
+ *                .secondMockCalledWith(value2)
+ *                .execute);
+ *
+ *    If the test fixture defines a `verify()` helper function which returns
+ *    `Step1::make(this)`, this can be simplified to:
+ *
+ *        verify().firstMockCalledWith(value1)
+ *                .secondMockCalledWith(value2)
+ *                .execute();
+ *
+ *    This is equivalent to the following calls made by the text function:
+ *
+ *        EXPECT_CALL(firstMock, FirstCall(value1));
+ *        EXPECT_CALL(secondMock, SecondCall(value2));
+ *        invokeFunctionUnderTest();

 This subdirectory contains Android's Vulkan loader, as well as some Vulkan-related tools useful to platform developers.
 
+## Documentation
+
+The former contents of doc/implementors_guide/ are now at https://source.android.com/devices/graphics/implement-vulkan.
+
 ## 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`.
+We generate several parts of the loader and tools driectly from the Vulkan Registry (external/vulkan-headers/registry/vk.xml). Code generation must be done manually because the generator is not part of the platform toolchain (yet?). Files named `foo_gen.*` are generated by the code generator.
 
- To run the generator:
+### Run The Code 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`
