+What's This All About?
+======================
+
+This directory contains the beginnings of what is hoped will be the
+new core of boto.  We want to move from using httplib to using
+requests.  We also want to offer full support for Python 2.6, 2.7, and
+3.x.  This is a pretty big change and will require some time to roll
+out but this module provides a starting point.
+
+What you will find in this module:
+
+* auth.py provides a SigV2 authentication packages as a args hook for requests.
+* credentials.py provides a way of finding AWS credentials (see below).
+* dictresponse.py provides a generic response handler that parses XML responses
+  and returns them as nested Python data structures.
+* service.py provides a simple example of a service that actually makes an EC2
+  request and returns a response.
+
+Credentials
+===========
+
+Credentials are being handled a bit differently here.  The following
+describes the order of search for credentials:
+
+1. If your local environment for has ACCESS_KEY and SECRET_KEY variables
+   defined, these will be used.
+
+2. If your local environment has AWS_CREDENTIAL_FILE defined, it is assumed
+   that it will be a config file with entries like this:
+
+   [default]
+   access_key = xxxxxxxxxxxxxxxx
+   sercret_key = xxxxxxxxxxxxxxxxxx
+
+   [test]
+   access_key = yyyyyyyyyyyyyy
+   secret_key = yyyyyyyyyyyyyyyyyy
+
+   Each section in the config file is called a persona and you can reference
+   a particular persona by name when instantiating a Service class.
+
+3. If a standard boto config file is found that contains credentials, those
+   will be used.
+
+4. If temporary credentials for an IAM Role are found in the instance
+   metadata of an EC2 instance, these credentials will be used.
+
+Trying Things Out
+=================
+To try this code out, cd to the directory containing the core module.
+
+    >>> import core.service
+    >>> s = core.service.Service()
+    >>> s.describe_instances()
+
+This code should return a Python data structure containing information
+about your currently running EC2 instances.  This example should run in
+Python 2.6.x, 2.7.x and Python 3.x.
