+# Custom method
+
+This is an example to show how to make a custom method.
+
+This example focus on the `TRACE` method, to send to a remote user all actions to a resource or its children.
+It uses the headers `Trace-Depth`, `Trace-Separator` and `Trace-Method` to customize the answer and the observed resources.
+
+The `ts` file and the `js` file are the same thing. The `js` file displays the example in JavaScript while the `ts` file displays the example in TypeScript.
