+# dotenv-expand
+
+<img src="https://raw.githubusercontent.com/motdotla/dotenv-expand/master/dotenv-expand.png" alt="dotenv-expand" align="right" />
+
+Dotenv-expand adds variable expansion on top of 
+[dotenv](http://github.com/motdotla/dotenv). If you find yourself needing to
+expand environment variables already existing on your machine, then
+dotenv-expand is your tool.
+
+[![BuildStatus](https://img.shields.io/travis/motdotla/dotenv-expand/master.svg?style=flat-square)](https://travis-ci.org/motdotla/dotenv-expand)
+[![NPM version](https://img.shields.io/npm/v/dotenv-expand.svg?style=flat-square)](https://www.npmjs.com/package/dotenv-expand)
+[![js-standard-style](https://img.shields.io/badge/code%20style-standard-brightgreen.svg?style=flat-square)](https://github.com/feross/standard)
+
+## Install
+
+```bash
+npm install dotenv --save
+npm install dotenv-expand --save
+```
+
+## Usage
+
+As early as possible in your application, require dotenv and dotenv-expand, and
+wrap dotenv-expand around dotenv.
+
+```js
+var dotenv = require('dotenv')
+var dotenvExpand = require('dotenv-expand')
+
+var myEnv = dotenv.config()
+dotenvExpand(myEnv)
+```
+
+See [test/.env](./test/.env) for examples of variable expansion in your `.env`
+file.
