-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

 root certificates from Mozilla to authenticate against, while the previous method only accepts a single
 certificate for a given server. This allows the client to connect to all public SSL servers.
 
-To use this feature in PlatformIO:
-1. create a certificate bundle as described in the document below, or obtain a pre-built one you trust:
-https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/protocols/esp_crt_bundle.html
-(gen_crt_bundle.py can be found in the /tools folder)
-   a. note: the full bundle will take up around 64k of flash space, but has minimal RAM usage, as only
-      the index of the certificates is kept in RAM
-2. Place the bundle under the file name "data/cert/x509_crt_bundle.bin" in your platformio project
-3. add "board_build.embed_files = data/cert/x509_crt_bundle.bin" in your platformio.ini
-4. add the following global declaration in your project:
-   extern const uint8_t rootca_crt_bundle_start[] asm("_binary_data_cert_x509_crt_bundle_bin_start");
-5. before initiating the first SSL connection, call
-   my_client.setCACertBundle(rootca_crt_bundle_start);
-
 To use this feature in Arduino IDE:
 If the Arduino IDE added support for embedding files in the meantime, then follow the instructions above.
-If not, you have three choices:
+If not, you have two choices:
-1. convert your project to PlatformIO
+1. create a makefile where you can add the idf_component_register() declaration to include the certificate bundle
-2. create a makefile where you can add the idf_component_register() declaration to include the certificate bundle
+2. Store the bundle as a SPIFFS file, but then you have to load it into RAM in runtime and waste 64k of precious memory
