//Backup
If you want to backup your files, navigate to your SIFU folder, where the .exe is located and then "Sifu\Content\Movies\SkillVideosOpti" - you can create a backup folder in this directory and copy every video already in it onto it.

(Keep in mind I couldn't recreate every move, so for now, "05_Action_PushCancel", "07_Action_ItemCatch" and "12_Action_OTGCounter" are placeholders)

//Installation
1- Navigate to your SIFU folder, where the .exe is located
2- Drag and drop the "Sifu" folder in the folder where the .exe is located
3- It will ask you to if you want to replace the files, make sure to backup if you want them!
4- Done!

//Restoration
If you somehow lost the files, you can verify cache files in your launcher to get them back.
