first you need to download the program off nexus mods[www.nexusmods.com] or github[github.com]
downloading from nexus mods supports me but github doesn't require an account so take your pick
if you wanna see some other unreal engine modding stuff you can also follow my github[github.com]

once downloaded you can run the executable (since it isn't signed it may be flagged as malware by windows but you can choose to run anyway - source code is on github[github.com] if you are worried)
select the location of your game in the folder dialog -
(by default this is C:\Program Files (x86)\Steam\steamapps\common\Pseudoregalia)
tick what you want to be randomised
click the generate and install seed button and next time you play you should have a randomised game :)
you can uninstall the seed by clicking the uninstall seed button
