 A simple Java Lambda based server-less application that implements a reimbursement use case, with AWS Lambda, AWS API Gateway, AWS SES, and AWS DynamoDB. Set up the project with Eclipse and AWS Toolkit plugin.
 
-## Getting Started
-### IDE Setup
-1. Open Eclipse
-2. Install the AWS Toolkit for Eclipse and set up your AWS access key id and secret access key: http://docs.aws.amazon.com/AWSToolkitEclipse/latest/ug/tke_setup_install.html
-3. Import project LambdaForm: Right click on the Package Explorer > Import > General > Existing Projects into Workspace. Do the same for LambdaSendMail and LambdaApproval.
-4. Sign up for AWS Lambda, API Gateway, DynamoDB, and SES (if you have not done so, yet).
+Please take a look at the wiki for a detailed [Getting Started - Step-by-Step](https://github.com/markusklems/aws-lambda-java-example/wiki/Getting-Started) guide.
 
-### Upload Lambda Functions
-1. Right click on the LambdaForm project folder > Amazon Web Services > Upload Function to AWS Lambda > Follow the steps in the wizard and create a new Lambda Function.
-2. Upload the Lambda Functions of the other two projects LambdaSendMail and LambdaApproval.
-3. Give the Lambda Functions an IAM role that allows access to DynamoDB and SES.
+## Getting Started (Short)
+1. Set up Eclipse, import the projects, and install the AWS Eclipse Toolkit plugin.
+2. Upload the Lambda Functions (Right click on project > Amazon Web Services > Upload Function to AWS Lambda)
+3. Set up a DynamoDB table 'lambda-reimbursment' with Hash Key 'employee_id' (String). Set the DynamoDB tables as event source for LambdaSendMail and LambdaApproval. Create an API method, so that a click on the link (HTTP GET) calls the LambdaApproval Function (with a parameter 'employee_id').
+4. Call the LambdaForm Function from Eclipse with the following JSON input:
+```{"employee_id":"1", "employee_name":"John Doh", "expense_type":"travel","amount": "456.75" }```
 
-### AWS Services setup
-1. Set up a DynamoDB table named 'lambda-reimbursment' with the Hash Key 'employee_id' of type String. In the example, the EU-WEST-1 region (Ireland) is chosen.
-2. In the AWS dashboard, go to Lambda > LambdaSendMail > Event source. Add an event source of type DynamoDB (table: lambda-reimbursment) with default settings.
-3. Do the same (as in step 2) for LambdaApproval.
-4. In the AWS dashboard, go to API Gateway and create a new API that points at the LambdaApproval Function. Create a Resource "reimbursment" and a GET method. Click on "Method Request" and add a query string parameter "id". Click on "Integration Request" and add a Mapping Template with content type "application/json" and Template:
-```
-{
-    "employee_id" : "$input.params('id')"
-}
-```
-Deploy the API.
+If the Lambda Function completes successfully, a new entry will be added to the DynamoDB table lambda-reimbursment.
+LambdaSendMail gets triggered by the DynamoDB stream (pull model) and sends an e-mail with the info that has been added to the table.
+If you have received the e-mail and click on the approval URL in the e-mail body, the LambdaApproval Function will be called and add an "approved" column entry to DynamoDB.
 
-### Run Lambda Functions
-1. Right click on the LambdaForm project folder > Amazon Web Services > Run Function on AWS Lambda > Enter a JSON object like this one:
-```{"employee_id":"1", "employee_name":"John Doh", "expense_type":"travel","amount": "456.75" }```
-2. If the Lambda Function completes successfully, a new entry will be added to the DynamoDB table lambda-reimbursment that you created in step 1 of the AWS Services setup.
-3. LambdaSendMail gets triggered by the DynamoDB stream (pull model) and sends an e-mail with the info that has been added to the table.
-4. If you have received the e-mail and click on the approval URL in the e-mail body, the LambdaApproval Function will be called and add an "approved" column entry to DynamoDB.
