You can use the [Arduino-ESP32 Online Documentation](https://docs.espressif.com/projects/arduino-esp32/en/latest/) to get all information about this project.
**Migration guide from version 2.x to 3.x is available [here](https://docs.espressif.com/projects/arduino-esp32/en/latest/migration_guides/2.x_to_3.0.html).**
**APIs compatibility with ESP8266 and Arduino-CORE (Arduino.cc) is explained [here](https://docs.espressif.com/projects/arduino-esp32/en/latest/libraries.html#apis).**
> ESP32-C2 is also supported by Arduino-ESP32 but requires rebuilding the static libraries. This is not trivial and requires a good understanding of the ESP-IDF
> build system. For more information, see the [Lib Builder documentation](https://docs.espressif.com/projects/arduino-esp32/en/latest/lib_builder.html).
For more details visit the [supported chips](https://docs.espressif.com/projects/arduino-esp32/en/latest/getting_started.html#supported-soc-s) documentation page.

We have set-up CI testing for external libraries for ESP32 Arduino core. You can check test results in the file [LIBRARIES_TEST](https://github.com/espressif/arduino-esp32/blob/gh-pages/LIBRARIES_TEST.md).
For more information and how to add your library to the test see [external library testing](https://docs.espressif.com/projects/arduino-esp32/en/latest/external_libraries_test.html) in the documentation.
See [contributing](https://docs.espressif.com/projects/arduino-esp32/en/latest/contributing.html) in the documentation for more information on how to contribute to the project.
