# _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.
