 # Serverless Step Functions
-[WIP]..
+Serverless plugin for AWS Step Functions.
+
+## Install
+Run `npm install` in your Serverless project.
+```
+$ npm install --save serverless-step-functions
+```
+
+Add the plugin to your serverless.yml file
+```yml
+plugins:
+  - serverless-step-functions
+```
+
+## Setup
+Write definitions yaml using Amazon States Language in a `stepFunctions` statement in serverless.yml.
+`Resource` statements refer to `functions` statements. Therefore, you do not need to write a function arn directly.
+
+```yml
+functions:
+  hellofunc:
+    handler: handler.hello
+
+stepFunctions:
+  hellostepfunc:
+    Comment: "A Hello World example of the Amazon States Language using an AWS Lambda Function"
+    StartAt: HelloWorld
+    States: 
+      HelloWorld: 
+        Type: Task
+        Resource: hellofunc
+        End: true
+```
+
