+# dotenv
+
+
+
+Dotenv is a zero-dependency module that loads environment variables from a `.env` file into [`process.env`](https://nodejs.org/docs/latest/api/process.html#process_process_env). Storing configuration in the environment separate from code is based on [The Twelve-Factor App](http://12factor.net/config) methodology.
+
+[](https://travis-ci.org/motdotla/dotenv)
+[](https://www.npmjs.com/package/dotenv)
+[](https://github.com/feross/standard)
+[](https://coveralls.io/github/motdotla/dotenv?branch=coverall-intergration)
+
+## Install
+
+```bash
+npm install dotenv --save
+```
+
+## Usage
+
+As early as possible in your application, require and configure dotenv.
+
+```javascript
+require('dotenv').config()
+```
+
+Create a `.env` file in the root directory of your project. Add
+environment-specific variables on new lines in the form of `NAME=VALUE`.
+For example:
+
+```
+DB_HOST=localhost
+DB_USER=root
+DB_PASS=s1mpl3
+```
+
+That's it.
+
+`process.env` now has the keys and values you defined in your `.env` file.
+
+```javascript
+var db = require('db')
+db.connect({
+ host: process.env.DB_HOST,
+ username: process.env.DB_USER,
+ password: process.env.DB_PASS
+})
+```
+
+### Preload
+
+If you are using iojs-v1.6.0 or later, you can use the `--require` (`-r`) command line option to preload dotenv. By doing this, you do not need to require and load dotenv in your application code.
+
+
+```bash
+$ node -r dotenv/config your_script.js
+```
+
+The configuration options below are supported as command line arguments in the format `dotenv_config_
