Adding an inadequate README file.

+=====
+
+**Kappa** is a command line tool that (hopefully) makes it easier to
+deploy, update, and test functions for AWS Lambda.
+
+There are quite a few steps involved in developing a Lambda function.
+You have to:
+
+* Write the function itself (Javascript only for now)
+* Create the IAM roles required by the Lambda function itself (the executing
+role) as well as the policy required by whoever is invoking the Lambda
+function (the invocation role)
+* Compress the function and any dependencies and upload it to AWS Lambda
+* Test the function with mock data
+* Retrieve the output of the function from CloudWatch Logs
+* Add an event source to the function
+* View the output of the live function
+
+Kappa tries to help you with some of this.  The IAM roles are created
+in a CloudFormation template and kappa takes care of creating, updating, and
+deleting the CloudFormation stack.  Kappa will also zip up the function and
+any dependencies and upload them to AWS Lambda.  It also sends test data
+to the uploaded function and finds the related CloudWatch log stream and
+displays the log events.  Finally, it will add the event source to turn
+your function on.
+
+Kappa is a command line tool.  The basic command is:
+
+    kappa --config <path to config file> <command>
+
+Where commands is one of:
+
+* deploy - deploy the CloudFormation template containing the IAM roles and zip the function and upload it to AWS Lambda
+* test - send test data to the new Lambda function
+* tail - display the most recent log events for the function
+* delete - delete the CloudFormation stack containing the IAM roles and delete the Lambda function
+
+The ``config file`` is a YAML format file containing all of the information
+about your Lambda function.
+
+An example project based on a Kinesis stream can be found in
+``samples/kinesis``.
