-Follow detailed instructions provided specifically for this example.
-
-Select the instructions depending on Espressif chip installed on your development board:
-
-- [ESP32 Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/stable/get-started/index.html)
-- [ESP32-S2 Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/get-started/index.html)
-
-
-## Example folder contents
-
-The project **hello_world** contains one source file in C language [hello_world_main.c](main/hello_world_main.c). The file is located in folder [main](main).
-
-ESP-IDF projects are built using CMake. The project build configuration is contained in `CMakeLists.txt` files that provide set of directives and instructions describing the project's source files and targets (executable, library, or both).
-
-Below is short explanation of remaining files in the project folder.
-
-```
-├── CMakeLists.txt
-├── pytest_hello_world.py      Python script used for automated testing
-├── main
-│   ├── CMakeLists.txt
-│   └── hello_world_main.c
-└── README.md                  This is the file you are currently reading
-```
-
-For more information on structure and contents of ESP-IDF projects, please refer to Section [Build System](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/build-system.html) of the ESP-IDF Programming Guide.
-
-## Troubleshooting
-
-* Program upload failure
-
-    * Hardware connection is not correct: run `idf.py -p PORT monitor`, and reboot your board to see if there are any output logs.
-    * The baud rate for downloading is too high: lower your baud rate in the `menuconfig` menu, and try again.
-
-## Technical support and feedback
-
-Please use the following feedback channels:
-
-* For technical queries, go to the [esp32.com](https://esp32.com/) forum
-* For a feature request or bug report, create a [GitHub issue](https://github.com/espressif/esp-idf/issues)
-
-We will get back to you as soon as possible.
