 WHEN TO UPDATE?
 
 - Keeping your copy of Dear ImGui updated regularly is recommended.

-  The library is fairly stable and regressions tends to be fixed fast when reported.
+- It is generally safe and recommended to sync to the latest commit in 'master' or 'docking'

 HOW TO UPDATE?
 
-- Overwrite every file except imconfig.h (if you have modified it).
-- You may also locally branch to modify imconfig.h and merge latest into your branch.
+- Update submodule or copy/overwrite every file.
+- About imconfig.h:
+  - You may modify your copy of imconfig.h, in this case don't overwrite it.
+  - or you may locally branch to modify imconfig.h and merge/rebase latest.
+  - or you may '#define IMGUI_USER_CONFIG "my_config_file.h"' globally from your build system to
+    specify a custom path for your imconfig.h file and instead not have to modify the default one.
 - Read the `Breaking Changes` section (in imgui.cpp or here in the Changelog).
 - If you have a problem with a missing function/symbols, search for its name in the code, there will likely be a comment about it.
-- If you are dropping this repository in your codebase, please leave the demo and text files in there, they will be useful.
+- If you are copying this repository in your codebase, please leave the demo and documentations files in there, they will be useful.
 - You may diff your previous Changelog with the one you just copied and read that diff.
 - You may enable `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in imconfig.h to forcefully disable legacy names and symbols.
   Doing it every once in a while is a good way to make sure you are not using obsolete symbols. Dear ImGui is in active development,

    For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI,
    where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches.
  - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right.
- - This codebase is also optimized to yield decent performances with typical "Debug" builds settings.
  - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected).
    If you get an assert, read the messages and comments around the assert.
- - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace.
- - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.
-   See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that.
-   However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase.
- - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!).
+ - This codebase aims to be highly optimized:
+   - A typical idle frame should never call malloc/free.
+   - We rely on a maximum of constant-time or O(N) algorithms. Limiting searches/scans as much as possible.
+   - We put particular energy in making sure performances are decent with typical "Debug" build settings as well.
+     Which mean we tend to avoid over-relying on "zero-cost abstraction" as they aren't zero-cost at all.
+ - This codebase aims to be both highly opinionated and highly flexible:
+   - This code works because of the things it choose to solve or not solve.
+   - C++: this is a pragmatic C-ish codebase: we don't use fancy C++ features, we don't include C++ headers,
+     and ImGui:: is a namespace. We rarely use member functions (and when we did, I am mostly regretting it now).
+     This is to increase compatibility, increase maintainability and facilitate use from other languages.
+   - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.
+     See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that.
+     We can can optionally export math operators for ImVec2/ImVec4 using IMGUI_DEFINE_MATH_OPERATORS, which we use internally.
+   - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction
+     (so don't use ImVector in your code or at our own risk!).
+   - Building: We don't use nor mandate a build system for the main library.
+     This is in an effort to ensure that it works in the real world aka with any esoteric build setup.
+     This is also because providing a build system for the main library would be of little-value.
+     The build problems are almost never coming from the main library but from specific backends.
 
 
  HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
  ----------------------------------------------
+ - Update submodule or copy/overwrite every file.
+ - About imconfig.h:
+   - You may modify your copy of imconfig.h, in this case don't overwrite it.
+   - or you may locally branch to modify imconfig.h and merge/rebase latest.
+   - or you may '#define IMGUI_USER_CONFIG "my_config_file.h"' globally from your build system to
+     specify a custom path for your imconfig.h file and instead not have to modify the default one.
+
  - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h)
  - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master".
  - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file.

  GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
  ---------------------------------------------------------------
+ - See https://github.com/ocornut/imgui/wiki/Getting-Started.
  - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.
  - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder.
