 Developers can use this library to send application specific state of execution to the host and receive commands or other type of info in the opposite direction at runtime.

 - Navigate to **View** > **Command Palette**.
 
 - Type **ESP-IDF: New Project**, select the command and choose ESP-IDF version to use.
 
 If you don't see the option, please review the setup in :ref:`Install ESP-IDF and Tools <installation>`.
 
-- A window will be open with settings to configure the project. Later you can choose from a list a ESP-IDF examples, go the **system** section and choose the ``app_trace_to_host``. You will see a **Create Project Using Example app_trace_to_host** button in the top and a description of the project below. Click the button and the project will be opened in a new window.

 For this example, the project has been already configured for application tracing purposes. On other projects you need to enable ``CONFIG_APPTRACE_DEST_TRAX`` and ``CONFIG_APPTRACE_ENABLE`` with the **ESP-IDF: SDK Configuration Editor** command.
 
+.. note::
+  For the ``app_trace_basic`` example to work properly, you need to add the following settings to your project's ``.vscode/settings.json`` file:
+
+  .. code-block:: json
+
+    {
+      "trace.poll_period": 0,
+      "trace.trace_size": 2048,
+      "trace.stop_tmo": 3,
+      "trace.wait4halt": 0,
+      "trace.skip_size": 0
+    }
+
+  These settings ensure the same tracing behavior as demonstrated in the example.
+
 - Configure, build and flash your project as explained in the :ref:`Build the project <build the project>`.
 
-- Click the ``ESP-IDF Explorer`` in the `Visual Studio Code Activity bar <https://code.visualstudio.com/docs/getstarted/userinterface>`_ (1). On the ``IDF APP TRACER`` section, click the ``Start App Trace`` (2). This will execute the extension's OpenOCD server and send the corresponding tracing commands to generate a tracing log. You can see the generated tracing log in the ``APP TRACE ARCHIVES`` named with ``Trace Log #1`` (3). Each time you execute ``Start App Trace`` a new tracing will be generated and shown in the archives list. You can also start tracing by running the **ESP-IDF: App Trace** command.
