-# Vulkan-Utility-Libraries
+# Vulkan-Utility-Libraries
+
+This repo was created to share code across various Vulkan repositories, solving long standing issues for Vulkan 
+SDK developers and users.
+
+## Historical Context
+
+The `Vulkan-ValidationLayers` contained many libraries and utilities that were useful for other Vulkan repositories, and became the primary mechanism for code sharing in the Vulkan ecosystem.
+
+This caused the `Vulkan-ValidationLayers` to have to maintain and export source code which was never intended for that purpose. This not only hindered development of the `Vulkan-ValidationLayers`, but would frequently break anyone depending on the source code due to the poorly located nature of it. On top of numerous other issues.
+
+This repository was created to facilitate official source deliverables that can be reliably used by developers.
+
+## Vulkan::LayerSettings
+
+The `Vulkan::LayerSettings` library was created to standardize layer configuration code for various SDK layer deliverables.
+
+- [Vulkan Validation Layers](https://github.com/KhronosGroup/Vulkan-ValidationLayers)
+- [Vulkan Extension Layer](https://github.com/KhronosGroup/Vulkan-ExtensionLayer/)
+- [Vulkan Profiles](https://github.com/KhronosGroup/Vulkan-Profiles)
+- [LunarG Tool Layers](https://github.com/LunarG/VulkanTools)
+    EX: `VK_LAYER_LUNARG_api_dump`, `VK_LAYER_LUNARG_screenshot` and `VK_LAYER_LUNARG_monitor`
+
+This is to ensure they all worked consistently with the 3 main methods of layer configuration.
+
+For more information see [layer_configuration.md](docs/layer_configuration.md).
+
+## Vulkan::UtilityHeaders
+
+The `Vulkan::UtilityHeaders` library contains header only files that provide useful functionality to developers:
+
+- `vk_dispatch_table.h`: Initializing instance/device dispatch tables
+- `vk_format_utils.h`: Utilities for `VkFormat`
+- `vk_struct_helper.hpp`: Utilities for vulkan structs
+- `vk_enum_string_helper.h`: Converts Vulkan enums into strings
