+Passing Extra Arguments to QEMU
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Use the ``--qemu-extra-args`` option to pass additional arguments directly to QEMU. This is useful when you need to enable advanced QEMU features or debugging options. For example:
+
+.. code-block:: console
+
+    idf.py qemu --qemu-extra-args="-d in_asm,cpu" monitor
+
+This command starts QEMU with the specified extra arguments. You can use this option to pass any valid QEMU command-line arguments, such as enabling debug output, configuring devices, or other advanced features.
+
+For more available QEMU options, please refer to the `official QEMU documentation <https://www.qemu.org/docs/master/>`_ or run ``idf.py qemu --help``.
