+# _Sample project_
+
+(See the README.md file in the upper level 'examples' directory for more information about examples.)
+
+This is the simplest buildable example. The example is used by command `idf.py create-project`
+that copies the project to user specified path and set it's name. For more information follow the [docs page](https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/build-system.html#start-a-new-project)
+
+
+
+## How to use example
+We encourage the users to use the example as a template for the new projects.
+A recommended way is to follow the instructions on a [docs page](https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/build-system.html#start-a-new-project).
+
+## Example folder contents
+
+The project **sample_project** contains one source file in C language [main.c](main/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
+├── main
+│   ├── CMakeLists.txt
+│   └── main.c
+└── README.md This is the file you are currently reading
+```
+Additionally, the sample project contains Makefile and component.mk files, used for the legacy Make based build system.
+They are not used or needed when building with CMake and idf.py.
