 A [node-fetch](https://github.com/bitinn/node-fetch) wrapper with support for cookies.
 It supports reading/writing from/to a JSON cookie jar and keeps cookies in memory until you call `CookieJar.save()` to reduce disk I/O.
 
-## Usage Example
+## Usage Examples
+### with file...
 ```javascript
 import {fetch, CookieJar} from "node-fetch-cookies";
 
 (async () => {
     // creates a CookieJar instance
-    let cookieJar = new CookieJar("rw", "jar.json");
+    const cookieJar = new CookieJar("rw", "jar.json");
 
     // usual fetch usage, except with one or multiple cookie jars as first parameter
-    const response = await fetch(cookieJar, "https://google.de");
+    const response = await fetch(cookieJar, "https://example.com");
 
     // save the received cookies to disk
     cookieJar.save();
 })();
 ```
 
+### ...or without
+```javascript
+import {fetch, CookieJar} from "node-fetch-cookies";
+
+(async () => {
+    const cookieJar = new CookieJar("rw");
+
+    // log in to some api
+    let response = await fetch(cookieJar, "https://example.com/api/login", {
+        method: "POST",
+        body: "credentials"
+    });
+
+    // do some requests you require login for
+    response = await fetch(cookieJar, "https://example.com/api/admin/drop-all-databases");
+
+    // and optionally log out again
+    response = await fetch(cookieJar, "https://example.com/api/logout");
+})();
