+This project provides a working configuration of NGINX configured to act as an authenticating gateway for the AWS Lambda service. This allows you to proxy a private Lambda function without requiring users to authenticate to it. Within the proxy layer, additional functionality can be configured such as:
 
 - Providing an authentication gateway using an alternative authentication
    system to Lambda functions
 - For internal/micro services that can't authenticate against the Lambda functions
    (e.g. don't have libraries available) the gateway can provide a means
    to accessing Lambda functions without authentication
-- Protecting Lambda function from arbitrary public access and traversal
-- Rate limiting Lambda functions
+- Protecting Lambda functions from arbitrary public access and traversal
+- [Rate limiting](http://nginx.org/en/docs/http/ngx_http_limit_req_module.html) Lambda functions
 - Protecting Lambda functions with a [WAF](https://docs.nginx.com/nginx-waf/)

 ## Getting Started
 
 Refer to the [Getting Started Guide](docs/getting_started.md) for how to build and run the gateway.
 
 ## Directory Structure and File Descriptions

 ## Development
 
-Refer to the [Development Guide](docs/development.md) for more information about
-extending or testing the gateway.
