 ## Usage
 
-Require it with a directory path to cache in, and then use it the same way you would use fetch.
+Require it and use it the same way you would use node-fetch:
 
 ```js
-const fetch = require('node-fetch-cache')('./path/to/cache/dir');
+const fetch = require('node-fetch-cache');
 
 fetch('http://google.com')
   .then(response => response.text())
   .then(text => console.log(text));
 ```
 
+The next time you `fetch('http://google.com')`, the response will be returned from the cache. No HTTP request will be made.
