- Create blank idf project (from one of the examples).
- Create blank ESP-IDF project (use sample_project from /examples/get-started) or choose one of the examples.

Option 1. Using Arduino setup() and loop()
******************************************
- The `idf.py menuconfig` has some Arduino options.
- On `Autostart Arduino setup and loop on boot`.
- If you enable these options, your main.cpp should be formated like any other sketch.
- Turn on `Autostart Arduino setup and loop on boot`.
- In main folder rename file `main.c` to `main.cpp`.
- In main folder open file `CMakeList.txt` and change `main.c` to `main.cpp` as described below.

- Otherwise, you need to implement ```app_main()``` and call ```initArduino();``` in it.
Option 2. Using ESP-IDF appmain()
*********************************
- You need to implement ``app_main()`` and call ``initArduino();`` in it.
Keep in mind that setup() and loop() will not be called in this case.
If you plan to base your code on examples provided in `examples <https://github.com/espressif/esp-idf/tree/master/examples>`_, please make sure to move the app_main() function in main.cpp from the files in the example.
