+# Keep
+
+It makes keeping config information pretty easy.
+
+## Install
+
+ gem install keep
+
+## Usage
+
+ require 'keep'
+ keep = Keep.new('config/settings.yml')
+ keep.set(:password,'Ellen Page')
+ keep.get(:password)
+
+Just tell Keep where to keep things, then give it a hash of what to keep and
+what the value is.
+
+Keep currently serializes to YAML (although different backends are likely to
+come next- pull requests welcome).
+
+## More
+
+ keep = Keep.new('config/settings.yml')
+ keep.present?(:password)
+
+## Other important information
+
+Nothing else is important.
