 - ``idf.py app``, ``idf.py bootloader``, ``idf.py partition_table`` can be used to build only the app, bootloader, or partition table from the project as applicable.
 - There are matching commands ``idf.py app-flash``, etc. to flash only that single part of the project to the ESP32.
 - ``idf.py -p PORT erase_flash`` will use esptool.py to erase the ESP32's entire flash chip.
-- ``idf.py size`` prints some size information about the app. ``size-components`` and ``size-files`` are similar commands which print more detailed per-component or per-source-file information, respectively.
+- ``idf.py size`` prints some size information about the app. ``size-components`` and ``size-files`` are similar commands which print more detailed per-component or per-source-file information, respectively. If you define variable ``-DOUTPUT_JSON=1`` when running CMake (or ``idf.py``), the output will be formatted as JSON not as human readable text.
 - ``idf.py reconfigure`` re-runs CMake_ even if it doesn't seem to need re-running. This isn't necessary during normal usage, but can be useful after adding/removing files from the source tree, or when modifying CMake cache variables. For example, ``idf.py -DNAME='VALUE' reconfigure`` can be used to set variable ``NAME`` in CMake cache to value ``VALUE``.
 
 The order of multiple ``idf.py`` commands on the same invocation is not important, they will automatically be executed in the correct order for everything to take effect (ie building before flashing, erasing before flashing, etc.).
