+The source code for the project (as well as this guide) is located in [this repository](https://github.com/cpp-gamedev/learn-vulkan). A `section/*` branch intends to reflect the state of the code at the end of a particular section of the guide. Bugfixes / changes are generally backported, but there may be some divergence from the current state of the code (ie, in `main`). The source of the guide itself is only up-to-date on `main`, changes are not backported.

 Vulkan is platform agnostic, which is one of the main reasons for its verbosity: it has to account for a wide range of implementations in its API. We shall be constraining our approach to Windows and Linux (x64 or aarch64), and focusing on discrete GPUs, enabing us to sidestep quite a bit of that verbosity. Vulkan 1.3 is widely supported by the target desktop platforms and reasonably recent graphics cards.

     1. While Vulkan is a C API, it offers an official C++ wrapper library with many quality-of-life features. This guide almost exclusively uses that, except at the boundaries of other C libraries that themselves use the C API (eg GLFW and VMA).
