Usually it works as dinput8.dll, but if it's not, there is a possibility to rename it(see the list of supported names above).

@@ -40,6 +40,35 @@ Put ASI files in game root directory, 'scripts' or 'plugins' folder.
 If configuration is necessary, global.ini file can be placed to 'scripts' or 'plugins' folder. It can be used alongside the chosen dll and if so, it is also possible to use dll name for ini file, e.g. version.dll/version.ini.
 [See example of global.ini here](https://github.com/ThirteenAG/Ultimate-ASI-Loader/blob/master/data/scripts/global.ini).
 
+## UPDATE FOLDER (Overload From Folder)
+
+It is possible to install mods that replace files via the `update` folder, allowing you to avoid actual file replacement.
+
+For example, if a mod replaces the file located at:
+
+```
+Resident Evil 5\nativePC_MT\Image\Archive\ChapterEnd11.arc
+```
+
+With Ultimate ASI Loader installed, you can create an `update` folder and place the file at:
+
+```
+Resident Evil 5\update\nativePC_MT\Image\Archive\ChapterEnd11.arc
+```
+
+To revert the game to its initial state, simply remove the `update` folder.
+
+Please note that the `update` folder is relative to the location of the ASI loader, so you need to adjust paths accordingly. For example:
+
+```
+\Gameface\Content\Movies\1080\GTA_SA_CREDITS_FINAL_1920x1080.mp4
+```
+
+Should be adjusted to:
+
+```
+\Gameface\Binaries\Win64\update\Content\Movies\1080\GTA_SA_CREDITS_FINAL_1920x1080.mp4
+```
