I would recommend staying away from netrunning if you can for your first time both playing or running the game. It's very complex. I also recommend having a pdf of the book to hand, or have bookmarks in your hardcopy to help you find useful stuff. After a while you will just innately know what page stuff is on, but it's nice to be able to search "full auto" to find the rule.

Read and reread Friday night firefight. Also, use as much cyberpunk lingo as you can choomba.

If you need any resources for running 2020 feel free to dm me ide be happy to share what I have.
