Obviously, it is important to download the ReShade itself aswell!

Install it using "FFVIIRemakeIntergrade/End/Binaries/Win64/ff7remake_.exe" as your executable

I suggest to install all the packages just in case if you fancy some fine tuning (and I didn't bother checking what packages are necessary for the preset to work!)

Paste the ReMidgar.ini to FFVIIRemakeIntergrade/End/Binaries/Win64 folder and change to the preset in ReShade interface.
