+Silencer
+========
+
+Silencer is a simple rack-middleware for Rails that can selectively disable logging on per-action basis.  It's based on a [blog post](http://dennisreimann.de/blog/silencing-the-rails-log-on-a-per-action-basis/) by Dennis Reimann.
+
+Installation
+------------
+
+Just add silencer to your Gemfile:
+
+gem 'silencer'
+
+Usage
+-----
+
+In your production environment (presumably):
+
+```ruby
+require 'silencer/logger'
+
+module MyApp
+  class Application < Rails::Application
+    config.middleware.swap Rails::Rack::Logger, Silencer::Logger, :silence => ["/noisy/action.json"]
+  end
+end
+```
+
+By default, Silencer's logger will serve as a drop-in replacement for Rails default logger, but you can also send it a 'X-SILENCE-LOGGER' header (with any value) and that will also produce the same behavior.
+
+Note on Patches/Pull Requests
+-----------------------------
+
+* Fork the project.
+* 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)
+* Send me a pull request. Bonus points for topic branches.
+
