Read the documentation and install each of the following gems after initialising a new rails application. I have provided some initialiser snippets from one of my Rails 5.2 projects with configuration that I'd like to be setup, but please read the documentation to verify the snippets are still constructed correctly based on current gem versions today.
- install pg (remove sqlite)
- install paper_trail
- install act_as_paranoid
- install rack-attack
class Rack::Attack
