 Allows you to enqueue version creation/deletion as a background job to avoid having business logic blocked by changelog writing.
@@ -15,20 +14,29 @@ First you'll need to setup a job for processing versions:
 ``` ruby
 # The class MUST be named this
 class VersionJob < ApplicationJob

+
+## Configuration
+In an initializer, you can specify whether you want to opt into this behavior on a per-model basis:
+
+``` ruby
+PaperTrail::Background::Config.configure do |config|
+  config.opt_in = true
 end
 ```
 
+If opt-in behavior is set to `true`, you can enable async paper trails by specifying `async: true` in a given model's paper trail options:
+
+``` ruby
+class SomeModel < ActiveRecord::Base
+  has_paper_trail async: true
+end
+```
