+# Contributing to rainger
+
+:metal::tada:Thank you for helping with rainger! :tada::metal:
+
+<br>
+
+Development from people like you makes projects great. In order to make cool things like we all want to, there are a few basic things to follow.
+
+<br>
+**PR's should be in response to an issue**. Please open an issue before posting your PR
+
+1. If the patch/pull request is small, hack it out and see if the community likes it.
+2. On the other hand, if it is large, ask me about it first. We don't want to see time wasted on things that won't get merged or are already underway
+
+<br>
+
+### Lint and test
+* Lint with [xo](https://github.com/sindresorhus/xo)
+* Test with [ava](https://github.com/sindresorhus/ava)
+
+```js
+npm test // performs both xo linting and ava testing
+```
+
+<br>
+
+The `xo` and `ava` commands are also decoupled via their respective `npm run` variants:
+```js
+npm run xo
+
+// or
+
+npm run ava
+```
+
+<br>
+
+Reach out with questions!
+
+Cheers! :beers:

+
+## Install
+
+```
+npm install --save rainger
+```
+
+<br>
+
+## Usage
+
+*assuming the current year from* `Date` * function is 2016*:
+```js
+const rainger = require('rainger');
+
+rainger(2016);
+//=> '2016'
+
+rainger(1999);
+//=> '1999 - 2016'
+```
+
+<br>
+
+## About
+
+I was tired of seeing websites in 2016 that said
+> © 2015
+
+or even worse
+>© 2012 - 2014
+
+Using `rainger`, you can set your copyright year once and have it change dynamically year-to-year. If you made your code in 2016, `rainger(2016)` will return `2016` until it is 2017, at which point `rainger(2016)` will return `2016 - 2017`
+
+<br>
+
+## API
+
+### rainger(target)
+
+##### target
+
+Type: `string` || `number`
+
+Description: This is the year you want your range to begin at.
+
+#### returns
+
+Type: `string`
