+# CasperJS AWS Lambda Template
+
+A [CasperJS](http://casperjs.org/) node.js app for [Amazon Lambda](http://aws.amazon.com/lambda/).
+Based on [node-lambda-template](https://github.com/rebelmail/node-lambda-template) using [node-lambda](https://github.com/rebelmail/node-lambda).
+The app includes a PhantomJS binary (`phantomjs`) compiled for AWS Linux (https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.8-linux-x86_64.tar.bz2).
+
+## Setup
+
+Install dependencies using npm. It'll install the AWS SDK as well as PhantomJS on the development machine.
+
+```shell
+npm install
+```
+
+## Usage
+
+After installing use the following `npm` commands as described below. They're only wrapping the `node-lambda` functionality to allow `node-lambda` to be installed only locally. Additional params can be provided using `-- args`. For a list of available options see the `node-lambda` [documentation](https://github.com/RebelMail/node-lambda).
+
+Run the setup command to generate the environment file with the configuration used for the Amazon Lambda function. Edit the resulting `.env.` file with your custom settings.
+```shell
+npm run setup
+```
+
+To run the function locally execute the following command.
+```shell
+npm run start
+```
+
+Run the following command to deploy the app to Amazon Lambda. 
+```shell
+npm run deploy
+```
+
+> **Note:** npm version 2.x or newer required to pass arguments to the scripts using `-- args`
