+The remove function should accept a key and remove the cached value associated with that key, if any. It is also safe for your caching delegate to remove values from the cache arbitrarily if desired (for example if you want to implement a TTL in the caching delegate).

+## Importing as an ES Module

+You can import this library as an ES module:

+import fetch from 'node-fetch-cache';

+fetch('http://google.com')
+  .then(response => response.text())
+  .then(text => console.log(text));

+
+The default import also doubles as a `fetchBuilder`, so you can use it like so if you want to customize the caching:
+
+```js
+import fetchBuilder from 'node-fetch-cache';
+
+const fetch = fetchBuilder.withCache(new fetchBuilder.MemoryCache({ ttl: 10000 }));
 
 fetch('http://google.com')
