+## Dear ImGui: Backends
+
+**The backends/ folder contains backends for popular platforms/graphics API, which you can use in
+your application or engine to easily integrate Dear ImGui.** Each backend is typically self-contained in a pair of files: imgui_impl_XXXX.cpp + imgui_impl_XXXX.h.
+
+- The 'Platform' backends are in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, windowing.<BR>
+  e.g. Windows ([imgui_impl_win32.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_win32.cpp)), GLFW ([imgui_impl_glfw.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_glfw.cpp)), SDL2 ([imgui_impl_sdl.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_sdl.cpp)), etc.
+
+- The 'Renderer' backends are in charge of: creating atlas texture, rendering imgui draw data.<BR>
+  e.g. DirectX11 ([imgui_impl_dx11.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx11.cpp)), OpenGL/WebGL ([imgui_impl_opengl3.cpp]((https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_opengl3.cpp)), Vulkan ([imgui_impl_vulkan.cpp]((https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_vulkan.cpp)), etc.
+
+- For some high-level frameworks, a single backend usually handle both 'Platform' and 'Renderer' parts.<BR>
+  e.g. Allegro 5 ([imgui_impl_allegro5.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_allegro5.cpp)), Marmalade ([imgui_impl_marmalade.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_marmalade.cpp)). If you end up creating a custom backend for your engine, you may want to do the same.
+
+An application usually combines 1 Platform backend + 1 Renderer backend + main Dear ImGui sources.
+For example, the [example_win32_directx11](https://github.com/ocornut/imgui/tree/master/examples/example_win32_directx11) application combines imgui_impl_win32.cpp + imgui_impl_dx11.cpp. See [EXAMPLES.MD](https://github.com/ocornut/imgui/blob/master/docs/EXAMPLES.md) for details.
+
+
+### What are backends
+
+Dear ImGui is highly portable and only requires a few things to run and render, typically:
+
+ - Required: providing mouse/keyboard inputs (fed into the `ImGuiIO` structure).
+ - Required: uploading the font atlas texture into graphics memory.
+ - Required: rendering indexed textured triangles with a clipping rectangle.
+
+ Extra features are opt-in, our backends try to support as many as possible:
+
+ - Optional: custom texture binding support.
+ - Optional: clipboard support.
+ - Optional: gamepad support.
+ - Optional: mouse cursor shape support.
+ - Optional: IME support.
+ - Optional: multi-viewports support.
+ etc.
+
+This is essentially what each backends are doing + obligatory portability cruft.
+
+It is important to understand the difference between the core Dear ImGui library (files in the root folder)
+and backends which we are describing here (backends/ folder).
+
+- Some issues may only be backend or platform specific.
+- You should be able to write backends for pretty much any platform and any 3D graphics API. 
+  e.g. you can get creative and use software rendering or render remotely on a different machine.
+
+

+### Recommended Backends
+
+If you are not sure which backend to use, the recommended platform/frameworks for portable applications:
+
+|Library |Website |Backend |Note |
+|--------|--------|--------|-----|
+| GLFW | https://github.com/glfw/glfw | imgui_impl_glfw.cpp | |
+| SDL2 | https://www.libsdl.org | imgui_impl_sdl.cpp | |
+| Sokol | https://github.com/floooh/sokol | [util/sokol_imgui.h](https://github.com/floooh/sokol/blob/master/util/sokol_imgui.h) | Lower-level than GLFW/SDL |
+
+
+### Using a custom engine?
+
+You will likely be tempted to start by rewrite your own backend using your own custom/high-level facilities...<BR>
+Think twice!
+
+If you are new to Dear ImGui, first try using the existing backends as-is.
+You will save lots of time integrating the library.
+You can LATER decide to rewrite yourself a custom backend if you really need to.
+In most situations, custom backends have less features and more bugs than the standard backends we provide.
+If you want portability, you can use multiple backends and choose between them either at compile time 
+or at runtime. 
+
+**Example A**: your engine is built over Windows + DirectX11 but you have your own high-level rendering
+system layered over DirectX11.<BR>
+Suggestion: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first.
+Once it works, if you really need it you can replace the imgui_impl_dx11.cpp code with a 
+custom renderer using your own rendering functions, and keep using the standard Win32 code etc.
+
+**Example B**: your engine runs on Windows, Mac, Linux and uses DirectX11, Metal, Vulkan respectively.<BR>
+Suggestion: use multiple generic backends!
+Once it works, if you really need it you can replace parts of backends with your own abstractions.
+
+**Example C**: your engine runs on platforms we can't provide public backends for (e.g. PS4/PS5, Switch), 
+and you have high-level systems everywhere.<BR>
+Suggestion: try using a non-portable backend first (e.g. win32 + underlying graphics API) to get
+your desktop builds working first. This will get you running faster and get your acquainted with
+how Dear ImGui works and is setup. You can then rewrite a custom backend using your own engine API.
+
+Also:
+The [multi-viewports feature](https://github.com/ocornut/imgui/issues/1542) of the 'docking' branch allows 
+Dear ImGui windows to be seamlessly detached from the main application window. This is achieved using an 
+extra layer to the Platform and Renderer backends, which allows Dear ImGui to communicate platform-specific 
+requests such as: "create an additional OS window", "create a render context", "get the OS position of this 
+window" etc. See 'ImGuiPlatformIO' for details.
+Supporting the multi-viewports feature correctly using 100% of your own abstractions is more difficult 
+than supporting single-viewport.
+If you decide to use unmodified imgui_impl_XXXX.cpp files, you can automatically benefit from
+improvements and fixes related to viewports and platform windows without extra work on your side.

+- Backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. (#3513)
+- Removed redirecting functions/enums names that were marked obsolete in 1.60 (April 2017):

+  - InputFloat (... int decimal_precision ...)  -> use InputFloat (... const char* format ...) with format = "%.Xf" where X was value for decimal_precision.
+  - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter.
+- If you were still using the old names, while you are cleaning up, considering enabling
+  IMGUI_DISABLE_OBSOLETE_FUNCTIONS in imconfig.h even temporarily to have a pass at finding
+  and removing up old API calls, if any remaining.

+platforms and graphics APIs.** They all use standard backends from the [backends/](https://github.com/ocornut/imgui/blob/master/backends) folder.
+
+You can find Windows binaries for some of those example applications at:
+  http://www.dearimgui.org/binaries
+
+
+### Getting Started
+
+Integration in a typical existing application, should take <20 lines when using standard backends.
+
+    At initialization:               
+      call ImGui::CreateContext()
+      call ImGui_ImplXXXX_Init() for each backend.
+
+    At the beginning of your frame:
+      call ImGui_ImplXXXX_NewFrame() for each backend.
+      call ImGui::NewFrame()
+
+    At the end of your frame:
+      call ImGui::Render()
+      call ImGui_ImplXXXX_RenderDrawData() for your Renderer backend.
+
+    At shutdown:
+      call ImGui_ImplXXXX_Shutdown() for each backend.
+      call ImGui::DestroyContext()
+
+Example (using [backends/imgui_impl_win32.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_win32.cpp) + [backends/imgui_impl_dx11.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx11.cpp)):

+### Miscallaneous
+
+**Building**
+
+Unfortunately in 2020 it is still tedious to create and maintain portable build files using external
+libraries (the kind we're using here to create a window and render 3D triangles) without relying on
+third party software. For most examples here we choose to provide:
+ - Makefiles for Linux/OSX
+ - Batch files for Visual Studio 2008+
+ - A .sln project file for Visual Studio 2012+
+ - Xcode project files for the Apple examples
+Please let us know if they don't work with your setup!
+You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
+directly with a command-line compiler.
+
+If you are interested in using Cmake to build and links examples, see:
+  https://github.com/ocornut/imgui/pull/1713 and https://github.com/ocornut/imgui/pull/3027
+
+**About mouse cursor latency**
+
+Dear ImGui has no particular extra lag for most behaviors,
+e.g. the value of 'io.MousePos' provided at the time of NewFrame() will result in windows being moved
+to the right spot at the time of EndFrame()/Render(). At 60 FPS your experience should be pleasant.
+
+However, consider that OS mouse cursors are typically drawn through a very specific hardware accelerated
+path and will feel smoother than the majority of contents rendered via regular graphics API (including,
+but not limited to Dear ImGui windows). Because UI rendering and interaction happens on the same plane 
+as the mouse, that disconnect may be jarring to particularly sensitive users.
+You may experiment with enabling the io.MouseDrawCursor flag to request Dear ImGui to draw a mouse cursor
+using the regular graphics API, to help you visualize the difference between a "hardware" cursor and a
+regularly rendered software cursor.
+However, rendering a mouse cursor at 60 FPS will feel sluggish so you likely won't want to enable that at
+all times. It might be beneficial for the user experience to switch to a software rendered cursor _only_
+when an interactive drag is in progress.
+
+Note that some setup or GPU drivers are likely to be causing extra display lag depending on their settings.
+If you feel that dragging windows feels laggy and you are not sure what the cause is: try to build a simple
+drawing a flat 2D shape directly under the mouse cursor!

 You will need a backend to integrate Dear ImGui in your app. The backend passes mouse/keyboard/gamepad inputs and variety of settings to Dear ImGui, and is in charge of rendering the resulting vertices.

 ### Integration
 
-On most platforms and when using C++, **you should be able to use a combination of the [imgui_impl_xxxx](https://github.com/ocornut/imgui/tree/master/examples) files without modification** (e.g. `imgui_impl_win32.cpp` + `imgui_impl_dx11.cpp`). If your engine supports multiple platforms, consider using more of the imgui_impl_xxxx files instead of rewriting them: this will be less work for you and you can get Dear ImGui running immediately. You can _later_ decide to rewrite a custom binding using your custom engine functions if you wish so.

 Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading one texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that. If you are an experienced programmer at ease with those concepts, it should take you less than two hours to integrate Dear ImGui in your custom engine. **Make sure to spend time reading the [FAQ](https://www.dearimgui.org/faq), comments, and some of the examples/ application!**

- dear imgui, v1.79
------------------------------------------------------------------------
- examples/README.txt
- (This is the README file for the examples/ folder. See docs/ for more documentation)
------------------------------------------------------------------------
-
-Dear ImGui is highly portable and only requires a few things to run and render:
-
- - Providing mouse/keyboard inputs
- - Uploading the font atlas texture into graphics memory
- - Providing a render function to render indexed textured triangles
- - Optional: clipboard support, mouse cursor supports, Windows IME support, etc.
- - Optional (Advanced,Beta): platform window API to use multi-viewport.
-
-This is essentially what the example bindings in this folder are providing + obligatory portability cruft.
-
-It is important to understand the difference between the core Dear ImGui library (files in the root folder)
-and examples bindings which we are describing here (examples/ folder).
-You should be able to write bindings for pretty much any platform and any 3D graphics API. With some extra
-effort you can even perform the rendering remotely, on a different machine than the one running the logic.
-
-This folder contains two things:
-
- - Example bindings for popular platforms/graphics API, which you can use as is or adapt for your own use.
-   They are the imgui_impl_XXXX files found in the examples/ folder.
-
- - Example applications (standalone, ready-to-build) using the aforementioned bindings.
-   They are the in the XXXX_example/ sub-folders.
-
-You can find binaries of some of those example applications at:
-  http://www.dearimgui.org/binaries
-
-
----------------------------------------
- GETTING STARTED
----------------------------------------
-
- - Please read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
-   Please read the comments and instruction at the top of each file.
-   Please read FAQ at http://www.dearimgui.org/faq
-
- - If you are using of the backend provided here, you can add the imgui_impl_xxx.cpp/h files
-   to your project and use them unmodified. Each imgui_impl_xxxx.cpp comes with its own individual
-   Changelog at the top of the .cpp files, so if you want to update them later it will be easier to
-   catch up with what changed.
-
- - Dear ImGui has no particular extra lag for most behaviors, e.g. the value of 'io.MousePos' provided in
-   NewFrame() will result at the time of EndFrame()/Render() in a moved windows rendered following that mouse
-   movement. At 60 FPS your experience should be pleasant.
-   However, consider that OS mouse cursors are typically drawn through a very specific hardware accelerated
-   path and will feel smoother than the majority of contents rendererd via regular graphics API (including,
-   but not limited to Dear ImGui windows). Because UI rendering and interaction happens on the same plane as
-   the mouse, that disconnect may be jarring to particularly sensitive users.
-   You may experiment with enabling the io.MouseDrawCursor flag to request Dear ImGui to draw a mouse cursor
-   using the regular graphics API, to help you visualize the difference between a "hardware" cursor and a
-   regularly rendered software cursor.
-   However, rendering a mouse cursor at 60 FPS will feel sluggish so you likely won't want to enable that at
-   all times. It might be beneficial for the user experience to switch to a software rendered cursor _only_
-   when an interactive drag is in progress.
-   Note that some setup or GPU drivers are likely to be causing extra display lag depending on their settings.
-   If you feel that dragging windows feels laggy and you are not sure what the cause is: try to build a simple
-   drawing a flat 2D shape directly under the mouse cursor.
-
-
----------------------------------------
- EXAMPLE BINDINGS
----------------------------------------
-
-Most the example bindings are split in 2 parts:
-
- - The "Platform" bindings, in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, windowing.
-   Examples: Windows (imgui_impl_win32.cpp), GLFW (imgui_impl_glfw.cpp), SDL2 (imgui_impl_sdl.cpp), etc.
-
- - The "Renderer" bindings, in charge of: creating the main font texture, rendering imgui draw data.
-   Examples: DirectX11 (imgui_impl_dx11.cpp), GL3 (imgui_impl_opengl3.cpp), Vulkan (imgui_impl_vulkan.cpp), etc.
-
- - The example _applications_ usually combine 1 platform + 1 renderer binding to create a working program.
-   Examples: the example_win32_directx11/ application combines imgui_impl_win32.cpp + imgui_impl_dx11.cpp.
-
- - Some bindings for higher level frameworks carry both "Platform" and "Renderer" parts in one file.
-   This is the case for Allegro 5 (imgui_impl_allegro5.cpp), Marmalade (imgui_impl_marmalade5.cpp).
-
- - If you use your own engine, you may decide to use some of existing bindings and/or rewrite some using
-   your own API. As a recommendation, if you are new to Dear ImGui, try using the existing binding as-is
-   first, before moving on to rewrite some of the code. Although it is tempting to rewrite both of the
-   imgui_impl_xxxx files to fit under your coding style, consider that it is not necessary!
-   In fact, if you are new to Dear ImGui, rewriting them will almost always be harder.
-
-   Example: your engine is built over Windows + DirectX11 but you have your own high-level rendering
-   system layered over DirectX11.
-     Suggestion: step 1: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first.
-     Once this work, _if_ you want you can replace the imgui_impl_dx11.cpp code with a custom renderer
-     using your own functions, etc.
-     Please consider using the bindings to the lower-level platform/graphics API as-is.
-
-   Example: your engine is multi-platform (consoles, phones, etc.), you have high-level systems everywhere.
-     Suggestion: step 1: try using a non-portable binding first (e.g. win32 + underlying graphics API)!
-     This is counter-intuitive, but this will get you running faster! Once you better understand how imgui
-     works and is bound, you can rewrite the code using your own systems.
-
- - Road-map: Dear ImGui 1.80 (WIP currently in the "docking" branch) will allows imgui windows to be
-   seamlessly detached from the main application window. This is achieved using an extra layer to the
-   platform and renderer bindings, which allows Dear ImGui to communicate platform-specific requests such as
-   "create an additional OS window", "create a render context", "get the OS position of this window" etc.
-   When using this feature, the coupling with your OS/renderer becomes much tighter than a regular imgui
-   integration. It is also much more complicated and require more work to integrate correctly.
-   If you are new to imgui and you are trying to integrate it into your application, first try to ignore
-   everything related to Viewport and Platform Windows. You'll be able to come back to it later!
-   Note that if you decide to use unmodified imgui_impl_xxxx.cpp files, you will automatically benefit
-   from improvements and fixes related to viewports and platform windows without extra work on your side.
-   See 'ImGuiPlatformIO' for details.

-
-Building:
-  Unfortunately in 2020 it is still tedious to create and maintain portable build files using external
-  libraries (the kind we're using here to create a window and render 3D triangles) without relying on
-  third party software. For most examples here we choose to provide:
-   - Makefiles for Linux/OSX
-   - Batch files for Visual Studio 2008+
-   - A .sln project file for Visual Studio 2012+
-   - Xcode project files for the Apple examples
-  Please let us know if they don't work with your setup!
-  You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
-  directly with a command-line compiler.
