Batman: Arkham Knight - Modding

Hey guys I had some questions regarding modding Batman: Arkham Knight. First off I’m a complete noob at modding, I’d love to be able to do at least something with this game. I know that being new to modding will complicate my goal in trying to mod this game because of the engine it runs on (so I’ve read). People recommend the Unity engine a lot but I was wondering even as a noobie if it’s a possibility to create mods for this game. If anyone can help in leading me in the right direction to getting started that’d be awesome. I’d also like to get a lot of feedback, like should I start with this game with this engine or should I try something else and work my way up?
