-- Moved Readme, Changelog and Todo files to the docs/ folder.
+- Moved README, CHANGELOG and TODO files to the docs/ folder.
   If you are updating dear imgui by copying files, take the chance to delete the old files.
 - Added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp.
   Re-ordered some of the code remaining in imgui.cpp in cleared chunks.
@@ -44,7 +44,9 @@ Changes:
   If you have any modifications to imgui.cpp, it is suggested that you first update to 1.63, then
   isolate your patches. You can peak at imgui_widgets.cpp from 1.64 to get a sense of what is included in it,
   then separate your changes into several patches that can more easily be applied to 1.64 on a per-file basis.
-- As a reminder, if you have any change to imgui.cpp it is a good habit to discuss them on the github
+  What I found worked nicely for me, was to open the diff of the old patches in an interactive merge/diff tool,
+  search for the corresponding function in the new code and apply the chunks manually. 
+- As a reminder, if you have any change to imgui.cpp it is a good habit to discuss them on the github,
   so a solution applicable on the Master branch can be found. If your company has changes that you cannot
   disclose you may also contact me privately.
