Yep, New PI time! And this one is better than ever
For Existing PI users:
1. Unzip the 7z file.
2. Place the mod file and folder into your mod folder and allow to replace the existing files
3. Grab the Flagfiles pictures and docs and copy them and put them in your Paradox Folder, where the PI cache is, click on that then, click on gfx and then again on flags and then paste the files and replace the existing files.
For New PI users:
1 and 2 are the same
3. Copy the flag files and create a new folder in your paradox folder, call it PI, then make a new folder called gfx and then a new folder inside of the gfx folder which should be inside of your PI folder called flags.
4. Paste the flag files.
