 ## Usage
 
-The best optimal approach is to add the minified inline to avoid extra http calls

 Or you can use the dist file
 
 ```html
-<script src="https://github.com/ezzarghili/xorq/releases/download/v1.1.0/xorq.min.js">

 </script>
 ```
 
 You can use the code this way
 
 ```javascript
-// available methods GET, POST, PUT, PATCH, DELETE
+// available methods HEAD, GET, POST, PUT, PATCH, DELETE
 // get resource
 xorq.get("http://example.com")
     .then(
