For installation: drop it into your 'Mods' directory, change the 'master' in the metadata to 'x-com-files'. Optionally make Starving Poet's randomisation changes, too.
Took me a while to figure out where the file was. For anyone else confused, it's the tiny-text zip file attached to the first post in this thread.
Thx for the installation procedure. FYI The 'master' he's taking about is the file called metadata.yml, it can be opened with a text editor like Notepad.
The mods folder was inside C:\Users\YOURNAMEHERE\Documents\OpenXcom\mods
