+## Bower
+
+{%= include("install-bower", {save: true}) %}
+
+## Notes
+
+Inspired by the python lib [range-regex](https://github.com/dimka665/range-regex), it has never been easier to validate numbers and number ranges with regex!
+
+The [unit tests generate 850,000 patterns](./test/test.js) to provide brute-force validation that the generated regex-ranges are correct.
+
+## Usage
+
+```js
+var toRegexRange = require('{%= name %}');
+
+var re = new RegExp(toRegexRange('1', '99'));
+re.test('50');
+//=> true
+```
+
+**Examples**
+
+```js
+toRegexRange('111', '555');
+//=> '11[1-9]|1[2-9]\d|[2-4]\d{2}|5[0-4]\d|55[0-5]'
+toRegexRange('5', '5');
+//=> '5'
+toRegexRange('5', '6');
+//=> '[5-6]'
+toRegexRange('51', '229');
+//=> '5[1-9]|[6-9]\d|1\d{2}|2[0-2]\d'
+```
+
+When the `min` is larger than the `max`, a regex logical `or` is returned:
+
+```js
+toRegexRange('51', '29');
+//=> '51|29'
+```
+
+Currently this does not support steps (increments) or zero-padding.

+# to-regex-range [](https://www.npmjs.com/package/to-regex-range) [](https://npmjs.org/package/to-regex-range) [](https://travis-ci.org/jonschlinkert/to-regex-range)
+
+> Returns a regex-compatible range from two numbers, min and max, with 855,412 generated unit tests to validate it's accuracy! Useful for creating regular expressions to validate numbers, ranges, years, etc. Returns a string, allowing the returned value to be used in regular expressions generated by other libraries.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save to-regex-range
+```
+
+## Bower
+
+Install with [bower](http://bower.io/)
+
+```sh
+$ bower install to-regex-range --save

Useful for creating regular expressions to validate numbers, ranges, years, etc. Returns a string, allowing the returned value to be used in regular expressions generated by other libraries.",
