For the Patch day, you don't need to use resorepless and its uninstall option thing.
You open Meta Injector before patching, go into its 3rd option (restore backup) and choose the last one which is highlighted green.
Then you close Meta Injector, open the launcher and let it patch. After its done patching you close the launcher, open meta injector and apply the mod using option 1 and keep structure... etc.
I myself do it this way everytime there is a patch/maintenance going on.
Resorepless itself is pretty much simply for the very first setup of the mod.
Its even recommended to use a different folder inside the paz directory.
Right now when using Resorepless you have the following path for your mod files:
(C:\[Steam]BlackDesert\paz\\files_to_patch\.resorepless\Character\) and inside there other folders like Model and texture.
If you now put in other mods, or textures inside that folder, and you later decide to change a setting inside resorepless, then everything inside this folderpath will be deleted and replaced with whatever your new settings contain.
Recomended is that you cut the Character folder out and paste it into the files_to_patch folder meaning that it looks like this:
C:\[Steam]BlackDesert\paz\\files_to_patch\Character
That way, whatever files you put in there yourself will stay, no matter how often you use resorepless.
