 ## Running Ruby Sinatra on AWS Lambda
 
-Demo code for running Ruby Sinatra on AWS Lambda
+This sample code helps get you started with a simple Sinatra web app deployed on AWS Lambda 
+
+What's Here
+-----------
+
+This sample includes:
+
+* README.md - this file
+* Gemfile - Gem requirements for the sample application
+* app/config.ru - this file contains configuration for Rack middleware
+* app/server.rb - this file contains the code for the sample service
+* app/views - this directory has the template files
+* spec/ - this directory contains the RSpec unit tests for the sample application
+* template.yml - this file contains the description of AWS resources used by AWS
+  CloudFormation to deploy your infrastructure
+
+Getting Started
+---------------
+
+These directions assume you want to develop on your local computer, and not
+from the Amazon EC2 instance itself. If you're on the Amazon EC2 instance, the
+virtual environment is already set up for you, and you can start working on the
+code.
+
+To work on the sample code, you'll need to clone your project's repository to your
+local computer. If you haven't, do that first. You can find instructions in the
+AWS CodeStar user guide.
+
+1. Install bundle
+
+        $ gem install bundle
+
+2. Install Ruby dependencies for this service
+
+        $ bundle install
+
+3. Download the Gems to the local vendor directory
+
+        $ bundle install --deployment
+        
+4. Create the deployment package (note: if you don't have a S3 bucket, you need to create one):
+
+        $ aws cloudformation package \
+            --template-file template.yaml \
+            --output-template-file serverless-output.yaml \
+            --s3-bucket { your-bucket-name }
+            
+    Alternatively, if you have SAM CLI installed, you can run the following command 
+    which will do the same
+
+        $ sam package \
+            --template-file template.yaml \
+            --output-template-file serverless-output.yaml \
+            --s3-bucket { your-bucket-name }
+            
+5. Deploying your application
+
+        $ aws cloudformation deploy --template-file serverless-output.yaml \
+            --stack-name { your-stack-name } \
+            --capabilities CAPABILITY_IAM
+
+    Or use SAM CLI
+
+        $ sam deploy \
+            --template-file serverless-output.yaml \
+            --stack-name { your-stack-name } \
+            --capabilities CAPABILITY_IAM
+
+
+What Do I Do Next?
+------------------
+
+If you have checked out a local copy of your repository you can start making changes to the sample code. 
+
+Learn more about Serverless Application Model (SAM) and how it works here: https://github.com/awslabs/serverless-application-model/blob/master/HOWTO.md
+
+AWS Lambda Developer Guide: http://docs.aws.amazon.com/lambda/latest/dg/deploying-lambda-apps.html
+
+How Do I Add Template Resources to My Project?
+------------------
+
+To add AWS resources to your project, you'll need to edit the `template.yml`
+file in your project's repository. You may also need to modify permissions for
+your project's worker roles. After you push the template change, AWS CloudFormation provisions the resources for you.
