 This one takes bits from both and is helping me understand gem and plugin development. It's built for rails 3 on the delayed_job 2.1.0.pre2 tag but don't see why it wouldn't work on rails 2 as well as it hooks into the callbacks of the Delayed::Job ActiveRecord class to turn workers on and off based on the creation and destruction of jobs.
 
 h2. Installation
 
-Add the gem to your Gemfile
+Add the gem to your project Gemfile and update your bundle
 
 <pre>
 gem "workless"
 </pre>
 
+Add your Heroku username / password as config vars to your Heroku instance, the same one you log in to Heroku with
+
+<pre>
+heroku config:add HEROKU_USER=<your username> HEROKU_PASSWORD=<your password>
+</pre>
+
+h2. Failing Jobs
+
+In the case of failed jobs Workless will only shut down the dj worker if all attempts have been tried. By default Delayed Job will try 25 times to process a job with ever increasing time delays between each unsucessful attempt. Because of this Workless configures Delayed Job to try failed jobs only 3 times to reduce the amount of time a worker can be running while trying to process them.
+
+h2. Configuration
+
+Workless can be disabled by using the null scaler that will ignore the workers requests to scale up and down. In an environment file add this:
+
+<pre>
+Delayed::Job.scaler = :null
+</pre>
+
+There are two other scalers included but generally these will be chosen for you based on if its running on Heroku
+
+<pre>
+Delayed::Job.scaler = :heroku
+Delayed::Job.scaler = :local
+</pre>
+
+The local scaler uses @adamwiggins rush library http://github.com/adamwiggins/rush to start and stop workers on a local machine

+* Please fork the project, as you can see there are no tests and at present I don't know how to go about adding them so any advice would be welcome.
 * Make your feature addition or bug fix.
-* Add tests for it. This is important so I don't break it in a
-  future version unintentionally.
 * Commit, do not mess with rakefile, version, or history.
   (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
