+# Description
+
+Adds [Data Bag][data_bag] support for older versions of *chef-solo*.
+
+# Requirements
+
+## Chef
+
+Chef versions lower than 0.10.4 may benefit. There is no reason to use this
+cookbook for Chef version 0.10.4 and higher as the feature is part of the
+core.
+
+## Platform
+
+Tested on Mac OS X 10.6.8 and Ubuntu 10.10 but should work any platform
+that is supported by Chef.
+
+## Cookbooks
+
+There are no external cookbook dependencies.
+
+# Recipes
+
+## default
+
+This recipe is a no-op and does nothing.
+
+# Attributes
+
+There are no attributes to define or configure.
+
+# Usage
+
+Simply include the cookbook in your chef repository and
+`libraries/solo_data_bags` will be loaded in the chef-solo run to add Data
+Bag support.
+
+# Development
+
+* Source hosted at [GitHub][repo]
+* Report issues/Questions/Feature requests on [GitHub Issues][issues]
+
+Pull requests are very welcome! Make sure your patches are well tested.
+Ideally create a topic branch for every seperate change you make.
