+# findup-sync  [![Build Status](https://travis-ci.org/js-cli/node-findup-sync.svg)](https://travis-ci.org/js-cli/node-findup-sync)  [![NPM version](https://badge.fury.io/js/findup-sync.svg)](http://badge.fury.io/js/findup-sync)
+
+> Find the first file matching a given pattern in the current directory or the nearest ancestor directory.
+
+Matching is done with [micromatch][], please report any matching related issues on that repository. 
+
+## Install with [npm](npmjs.org)
+
+```bash
+npm i findup-sync --save
+```
+
+## Usage
+
+```js
+var findup = require('findup-sync');
+findup(patternOrPatterns [, micromatchOptions]);
+
+// Start looking in the CWD.
+var filepath1 = findup('{a,b}*.txt');
+
+// Start looking somewhere else, and ignore case (probably a good idea).
+var filepath2 = findup('{a,b}*.txt', {cwd: '/some/path', nocase: true});
+```
+
+* `patterns` **{String|Array}**: Glob pattern(s) or file path(s) to match against.    
+* `options` **{Object}**: Options to pass to [micromatch]. Note that if you want to start in a different directory than the current working directory, specify a `cwd` property here.    
+* `returns` **{String}**: Returns the first matching file.
+
+## Running tests
+
+Install dev dependencies:
+
+```bash
+npm i -d && npm test
+```
+
+## Contributing
+
+In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using [Grunt](http://gruntjs.com/)
+
+For bugs and feature requests, [please create an issue](https://github.com/cowboy/node-findup-sync/issues).
