+    @@@@@@@@
+
+    For targets that support USB-Serial-JTAG, both the USB-Serial-JTAG and UART console output are enabled by default. If you only need one console, you can reduce the binary size and RAM usage by doing the following:
+
+    1. Disable the secondary console by setting :ref:`CONFIG_ESP_CONSOLE_SECONDARY` to ``CONFIG_ESP_CONSOLE_SECONDARY_NONE``.
+    2. Set :ref:`CONFIG_ESP_CONSOLE_UART` to use one of the following:
+
+      * ``UART`` reduces the binary size by around 2.5 KB.
+      * ``USB-Serial-JTAG`` reduces the binary size by around 10 KB and DRAM usage by around 1.5 KB.
+
+    Please note that these size reductions assume the UART/USB-Serial-JTAG driver code is not pulled into the app, if you already use these drivers for other purposes then the savings will be smaller.
