+# yn [![Build Status](https://travis-ci.org/sindresorhus/yn.svg?branch=master)](https://travis-ci.org/sindresorhus/yn)
+
+> Parse yes/no like values
+
+Useful for validating answers of a CLI prompt.

+
+The following case-insensitive values are recognized:
+
+```js
+'y', 'yes', 'true', true, '1', 1, 'n', 'no', 'false', false, '0', 0

+
+*Enable lenient mode to gracefully handle typos.*

+
+
+## Usage
+
+```js
+const yn = require('yn');

+yn('abomasum');
+//=> null
+
+yn('abomasum', {default: false});
+//=> false
+
+yn('mo', {lenient: true});
+//=> false
+```
+
+Unrecognized values return `null`.
+
+
+## API
+
+### yn(input, [options])
+
+#### input
