+Custom Reset Method
+-------------------
+
+To overwrite predefined reset method for uploading please use :ref:`projectconf_extra_script`.
+For example, default reset method for ``esp12e`` board is ``nodemcu``. Let's
+overwrite it to ``ck``:
+
+* :ref:`projectconf`
+
+    .. code-block:: ini
+
+        [env:esp12e]
+        platform = espressif
+        framework = arduino
+        board = esp12e
+        extra_script = extra_script.py
+
+
+* ``extra_script.py`` should be located on the same level as :ref:`projectconf`
+
+    .. code-block:: python
+
+        from SCons.Script import DefaultEnvironment
+
+        env = DefaultEnvironment()
+        env['BOARD_OPTIONS']['upload']['resetmethod'] = 'ck'
