+Environment Variables
+=====================
+
+Some environment variables can be specified whilst calling ``make`` allowing users to **override arguments without needing to reconfigure them using** ``make menuconfig``.
+
++-----------------+--------------------------------------------------------------+
+| Variables       | Description & Usage                                          |
++=================+==============================================================+
+| ``ESPPORT``     | Overrides the serial port used in ``flash`` and ``monitor``. |
+|                 |                                                              |
+|                 | Examples: ``make flash ESPPORT=/dev/tty/USB0``,              |
+|                 | ``make monitor ESPPORT=COM1``                                |
++-----------------+--------------------------------------------------------------+
+| ``ESPBAUD``     | Overrides the serial baud rate when flashing the ESP32.      |
+|                 |                                                              |
+|                 | Example: ``make flash ESPBAUD=9600``                         |
++-----------------+--------------------------------------------------------------+
+| ``MONITORBAUD`` | Overrides the serial baud rate used when monitoring.         |
+|                 |                                                              |
+|                 | Example: ``make monitor MONITORBAUD=9600``                   |
++-----------------+--------------------------------------------------------------+
+
+.. note::
+    Users can export environment variables (e.g. ``export ESPPORT=/dev/tty/USB0``).
+    All subsequent calls of ``make`` within the same terminal session will use 
+    the exported value given that the variable is not simultaneously overridden.
