 ## Overview
 
 Given any number of css file paths, for each file path, this module will:
+
 1. fetch the file at the path
 2. fetch a name and version from the nearest package.json to the file
-3. bundle the css found in the file (resolving any @import statements and inlining them)

 4. put all this together in an object (See Output data format below)
 
 The module provides a readable stream of the resulting objects.

 ## Usage
 
 ### Require the writer
+
 ```js
-const CssWriter = require('asset-pipe-css-writer')
+const CssWriter = require('asset-pipe-css-writer');
 ```
 
 ### Instantiating the writer
 
 Either pass a path to a single css file:
+
 ```js
-const writer = new CssWriter('/path/to/css/file.css')
+const writer = new CssWriter('/path/to/css/file.css');
 ```
 
 Or pass an array of paths to css files:
+
 ```js
-const writer = new CssWriter(['/path/to/css/file1.css', '/path/to/css/file2.css'])
+const writer = new CssWriter([
+    '/path/to/css/file1.css',
+    '/path/to/css/file2.css',
+]);
 ```
 
 ### Consuming content from the writer
 
-The writer is a readable stream in object mode so in order to access the data you may register a data handler
-and listen for objects to be passed to the handler:
