## Initialize
First we need to initialize Vulkan. You should already have done so if you're following the (vulkan-tutorial)[https://vulkan-tutorial.com/]. After getting Vulkan running, we can start an ImGui context. It's recommended to create a seperate `VkDescriptorPool`, `VkRenderPass`, `VkCommandBuffer`, and `VkFramebuffer`.

After starting an ImGui context, we give ImGui some of the application Vulkan bindings through an `ImGui_ImplVulkan_InitInfo` struct. We then call `ImGui_ImplVulkan_Init()` passing in a pointer to the `ImGui_ImplVulkan_InitInfo` and a `VkRenderPass`. This will initalize Vulkan for ImGui.

We then upload font textures to the GPU.

### Ending Frame
When we end the frame, we want to build the model so we can render this to the screen.
```c++
ImGuiIO& io = ::ImGui::GetIO();
ImGuiIO& io = ImGui::GetIO();
ImGui::Render();
if (io.ConfigFlags & ImGuiConfigFlags_ViewportsEnable){
