From the introduction:
This is an "introductory adventure" for A Flask Full of Gasoline. That means it's got a bunch of hand-holding along the way to help you run your first big fuckup.
Basically, this booklet runs you through a quick round of violence, a meeting with the boss, and another two rounds of violence with the opportunity to burn some shit along the way.
This game is available as a free download from 1KM1KT, see the RPG level entry for the link.
