-PlatformIO is a professional collaborative platform for embedded development. It has out-of-the-box support for ESP32 SoCs and allows working with Arduino ESP32 as well as ESP-IDF from Espressif without changing your development environment. PlatformIO includes lots of instruments for the most common development tasks such as debugging, unit testing, and static code analysis.
-
-.. warning:: Integration of the Arduino Core ESP32 project in PlatformIO is maintained by PlatformIO developers. Arduino Core ESP32 Project Team cannot support PlatformIO-specific issues. Please report these issues in official `PlatformIO repositories <https://github.com/platformio>`_.
-
-A detailed overview of the PlatformIO ecosystem and its philosophy can be found in `the official documentation <https://docs.platformio.org/en/latest/core/index.html>`_.
-
-PlatformIO can be used in two flavors:
-
-- `PlatformIO IDE <https://platformio.org/platformio-ide>`_ is a toolset for embedded C/C++ development available on Windows, macOS and Linux platforms
-
-- `PlatformIO Core (CLI) <https://docs.platformio.org/en/latest/core/index.html>`_ is a command-line tool that consists of a multi-platform build system, platform and library managers and other integration components. It can be used with a variety of code development environments and allows integration with cloud platforms and web services
-
-To install PlatformIO, you can follow this Getting Started, provided at `docs.platformio.org`_.
-
-Using the stable code
-*********************
-
-.. note::
-   A detailed overview of supported development boards, examples and frameworks can be found on `the official Espressif32 dev-platform page <https://registry.platformio.org/platforms/platformio/espressif32>`_ in the PlatformIO Registry.
-
-The most reliable and easiest way to get started is to use the latest stable version of the ESP32 development platform that passed all tests/verifications and can be used in production.
-
-Create a new project and select one of the available boards. You can change after by changing the `platformio.ini <https://docs.platformio.org/en/latest/projectconf/index.html>`_ file.

-How to update to the latest code
-********************************
-
-To test the latest Arduino ESP32, you need to change your project *platformio.ini* accordingly.
-The following configuration uses the upstream version of the Espressif development platform and the latest Arduino core directly from the Espressif GitHub repository:
-
-.. code-block:: bash
-
-   [env:esp32-c3-devkitm-1]
-   platform = https://github.com/platformio/platform-espressif32.git
-   board = esp32-c3-devkitm-1
-   framework = arduino
-   platform_packages =
-       framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32#master
