+# Hello World Example
+
+Starts a FreeRTOS task to print "Hello World".
+
+(See the README.md file in the upper level 'examples' directory for more information about examples.)
+
+## How to use example
+
+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)

+
+
+## 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.
