          LoggableActivity installation completed successfully!

          Quick Start:

          1. include hooks to the model we want to log.
            class MY_MODEL < ApplicationRecord
              include LoggableActivity::Hooks

          2. Update `config/application.rb
            config.loggable_activity = ActiveSupport::OrderedOptions.new
            config.loggable_activity.actor_display_name = :email
            config.loggable_activity.current_user_model_name = 'User'
            LoggableActivity::Configuration.load_config_file('config/loggable_activity.yaml')

          3. Include current_user ApplicationController
            class ApplicationController < ActionController::Base
              include LoggableActivity::CurrentUser

          4. Update the 'config/loggable_activity.yaml' file with the necessary configuration.

          5. Run the migration to create the necessary tables.
