+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');

-## Usage
-
-```js
-findup(patternOrPatterns [, minimatchOptions])
-```
+* `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.
 
-### patternOrPatterns
-Type: `String` or `Array`  
-Default: none
+## Running tests
 
-One or more wildcard glob patterns. Or just filenames.
+Install dev dependencies:
