-create -> create : Generate release notes
-create -> github : Create new draft release, associated with tag and with the notes
-note right
-Draft releases are not public facing, only those with write access can see them!

-alt all-artifacts-uploaded? case
-  build -> github : Publish the release
-  user -> github : Can now download the artifacts on the published release
-end
-note right 
-This is the only area where an eventual consistency issue is apparent
-It is because GitHub does not fire events for when draft releases are edited
-This is glossed over in the initial impl and can be improved and be made eventually consistent as well

+
+# Problem
+
+Memory allocation and resource (buffer and texture) creation in new, explicit graphics APIs (Vulkan® and Direct3D 12) is difficult comparing to older graphics APIs like Direct3D 11 or OpenGL® because it is recommended to allocate bigger blocks of memory and assign parts of them to resources. [Vulkan Memory Allocator](https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator/) is a library that implements this functionality for Vulkan. It is available online since 2017 and it is successfully used in many software projects, including some AAA game studios. This is an equivalent library for D3D12.
+
+# Features
+
+This library can help developers to manage memory allocations and resource creation by offering function `Allocator::CreateResource` similar to the standard `ID3D12Device::CreateCommittedResource`. It internally:
+
+- Allocates and keeps track of bigger memory heaps, used and unused ranges inside them, finds best matching unused ranges to create new resources there as placed resources.
+- Automatically respects size and alignment requirements for created resources.
+- Automatically handles resource heap tier - whether it's `D3D12_RESOURCE_HEAP_TIER_1` that requires to keep certain classes of resources separate or `D3D12_RESOURCE_HEAP_TIER_2` that allows to keep them all together.
+
+Additional features:
+
+- Well-documented - description of all classes and functions provided, along with chapters that contain general description and example code.
+- Thread-safety: Library is designed to be used in multithreaded code.
+- Configuration: Fill optional members of `ALLOCATOR_DESC` structure to provide custom CPU memory allocator and other parameters.
+- Customization and integration with custom engines: Predefine appropriate macros to provide your own implementation of external facilities used by the library, like assert, mutex, and atomic.
+- Support for resource aliasing (overlap).
+- Custom memory pools: Create a pool with desired parameters (e.g. fixed or limited maximum size, custom `D3D12_HEAP_PROPERTIES` and `D3D12_HEAP_FLAGS`) and allocate memory out of it.
+- Linear allocator: Create a pool with linear algorithm and use it for much faster allocations and deallocations in free-at-once, stack, double stack, or ring buffer fashion.
+- Defragmentation: Let the library move data around to free some memory blocks and make your allocations better compacted.
+- Statistics: Obtain brief or detailed statistics about the amount of memory used, unused, number of allocated heaps, number of allocations etc. - globally and per memory heap type. Current memory usage and budget as reported by the system can also be queried.
+- Debug annotations: Associate custom `void* pPrivateData` and debug `LPCWSTR pName` with each allocation.
+- JSON dump: Obtain a string in JSON format with detailed map of internal state, including list of allocations, their string names, and gaps between them.
+- Convert this JSON dump into a picture to visualize your memory using attached Python script.
+- Virtual allocator - an API that exposes the core allocation algorithm to be used without allocating real GPU memory, to allocate your own stuff, e.g. sub-allocate pieces of one large buffer.
+
+# Prerequisites
+
+- Self-contained C++ library in single pair of H + CPP files. No external dependencies other than standard C, C++ library and Windows SDK. Some features of C++14 used. STL containers, C++ exceptions, and RTTI are not used.
+- Object-oriented interface in a convention similar to D3D12.
+- Error handling implemented by returning `HRESULT` error codes - same way as in D3D12.
+- Interface documented using Doxygen-style comments.
+
+# Example
+
+Basic usage of this library is very simple. Advanced features are optional. After you created global `Allocator` object, a complete code needed to create a texture may look like this:
+
+```cpp
+D3D12_RESOURCE_DESC resourceDesc = {};
+resourceDesc.Dimension = D3D12_RESOURCE_DIMENSION_TEXTURE2D;
+resourceDesc.Alignment = 0;
+resourceDesc.Width = 1024;
+resourceDesc.Height = 1024;
+resourceDesc.DepthOrArraySize = 1;
+resourceDesc.MipLevels = 1;
+resourceDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
+resourceDesc.SampleDesc.Count = 1;
+resourceDesc.SampleDesc.Quality = 0;
+resourceDesc.Layout = D3D12_TEXTURE_LAYOUT_UNKNOWN;
+resourceDesc.Flags = D3D12_RESOURCE_FLAG_NONE;
+
+D3D12MA::ALLOCATION_DESC allocDesc = {};
+allocDesc.HeapType = D3D12_HEAP_TYPE_DEFAULT;
+
+D3D12Resource* resource;
+D3D12MA::Allocation* allocation;
+HRESULT hr = allocator->CreateResource(
+    &allocDesc, &resourceDesc,
+    D3D12_RESOURCE_STATE_COPY_DEST, NULL,
+    &allocation, IID_PPV_ARGS(&resource));
+```
+
+With this one function call:
+
+1. `ID3D12Heap` memory block is allocated if needed.
+2. An unused region of the memory block is reserved for the allocation.
+3. `ID3D12Resource` is created as placed resource, bound to this region.
+
+`Allocation` is an object that represents memory assigned to this texture. It can be queried for parameters like offset and size.
+
+# Binaries
+
+The release comes with precompiled binary executable for "D3D12Sample" application which contains test suite. It is compiled using Visual Studio 2019, so it requires appropriate libraries to work, including "MSVCP140.dll", "VCRUNTIME140.dll", "VCRUNTIME140_1.dll". If its launch fails with error message telling about those files missing, please download and install [Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads), "x64" version.

-// About Desktop OpenGL function loaders:
-//  Modern desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.
-//  Helper libraries are often used for this purpose! Here we are supporting a few common ones (gl3w, glew, glad).
-//  You may use another loader/header of your choice (glext, glLoadGen, etc.), or chose to manually implement your own.

-//  The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
-//  On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"

-// (minor and older changes stripped away, please see git history for details)
-//  2018-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
-//  2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
-//  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-//  2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
-//  2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
-//  2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
-//  2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
-//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
-//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-//  2016-05-07: DirectX11: Disabling depth-write.

-// dear imgui: Renderer for modern OpenGL with shaders / programmatic pipeline
-// - Desktop GL: 2.x 3.x 4.x
-// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
-// This needs to be used along with a Platform Binding (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-//  [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
-//  [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
-//  [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bits indices.
-
-// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
-// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
-// https://github.com/ocornut/imgui
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-//  2019-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
-//  2019-09-22: OpenGL: Detect default GL loader using __has_include compiler facility.
-//  2019-09-16: OpenGL: Tweak initialization code to allow application calling ImGui_ImplOpenGL3_CreateFontsTexture() before the first NewFrame() call.
-//  2019-05-29: OpenGL: Desktop GL only: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
-//  2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-//  2019-03-29: OpenGL: Not calling glBindBuffer more than necessary in the render loop.
-//  2019-03-15: OpenGL: Added a dummy GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized GL function loaders early.
-//  2019-03-03: OpenGL: Fix support for ES 2.0 (WebGL 1.0).
-//  2019-02-20: OpenGL: Fix for OSX not supporting OpenGL 4.5, we don't try to read GL_CLIP_ORIGIN even if defined by the headers/loader.
-//  2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
-//  2019-02-01: OpenGL: Using GLSL 410 shaders for any version over 410 (e.g. 430, 450).
-//  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-//  2018-11-13: OpenGL: Support for GL 4.5's glClipControl(GL_UPPER_LEFT) / GL_CLIP_ORIGIN.
-//  2018-08-29: OpenGL: Added support for more OpenGL loaders: glew and glad, with comments indicative that any loader can be used.
-//  2018-08-09: OpenGL: Default to OpenGL ES 3 on iOS and Android. GLSL version default to "#version 300 ES".
-//  2018-07-30: OpenGL: Support for GLSL 300 ES and 410 core. Fixes for Emscripten compilation.
-//  2018-07-10: OpenGL: Support for more GLSL versions (based on the GLSL version string). Added error output when shaders fail to compile/link.
-//  2018-06-08: Misc: Extracted imgui_impl_opengl3.cpp/.h away from the old combined GLFW/SDL+OpenGL3 examples.
-//  2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
-//  2018-05-25: OpenGL: Removed unnecessary backup/restore of GL_ELEMENT_ARRAY_BUFFER_BINDING since this is part of the VAO state.
-//  2018-05-14: OpenGL: Making the call to glBindSampler() optional so 3.2 context won't fail if the function is a NULL pointer.
-//  2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplOpenGL3_Init() so user can override the GLSL version e.g. "#version 150".
-//  2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context.
-//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplSdlGL3_RenderDrawData() in the .h file so you can call it yourself.
-//  2018-01-07: OpenGL: Changed GLSL shader version from 330 to 150.
-//  2017-09-01: OpenGL: Save and restore current bound sampler. Save and restore current polygon mode.
-//  2017-05-01: OpenGL: Fixed save and restore of current blend func state.
-//  2017-05-01: OpenGL: Fixed save and restore of current GL_ACTIVE_TEXTURE.
-//  2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.
-//  2016-07-29: OpenGL: Explicitly setting GL_UNPACK_ROW_LENGTH to reduce issues because SDL changes it. (#752)

+     The default value is 16 MB = (1 << 24) bytes.
+     It's recommended to use the dictionary that is larger than 4 KB and
+     that can be calculated as (1 << N) or (3 << N) sizes.
+
+lc - The number of literal context bits (high bits of previous literal).
+     It can be in the range from 0 to 8. The default value is 3.

+lp - The number of literal pos bits (low bits of current position for literals).

+     The lp switch is intended for periodical data when the period is equal to 2^lp.
+     For example, for 32-bit (4 bytes) periodical data you can use lp=2. Often it's
+     better to set lc=0, if you change lp switch.
+
+pb - The number of pos bits (low bits of current position).
+     It can be in the range from 0 to 4. The default value is 2.
+     The pb switch is intended for periodical data when the period is equal 2^pb.
+
+fb - Word size (the number of fast bytes).
+     It can be in the range from 5 to 273. The default value is 32.
+     Usually, a big number gives a little bit better compression ratio and
+     slower compression process.
+
+numThreads - The number of thereads. 1 or 2. The default value is 2.
