# wasm-micro-runtime as ESP-IDF component
You can build an ESP-IDF project with wasm-micro-runtime as a component:
- Make sure you have the ESP-IDF properly installed and setup
- In particular have the following paths set:
- `WAMR_PATH` to point to your wasm-micro-runtime repository
- `IDF_PATH` to point to your ESP-IDF
- `source $IDF_PATH/export.sh`
- Create a new project, e.g.: `idf.py create-project wamr-hello`
- In the newly created project folder edit the `CMakeList.txt`:
```
cmake_minimum_required(VERSION 3.5)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
set (COMPONENTS ${IDF_TARGET} main freertos esptool_py wamr)
list(APPEND EXTRA_COMPONENT_DIRS "$ENV{WAMR_PATH}/build-scripts/esp-idf")
project(wamr-hello)
```
- Develop your project in it's `main` component folder.
You can find an example [here](../../product-mini/platforms/esp-idf).
- Set target platform: `idf.py set-target esp32c3`
- Build: `idf.py build`
- Flash: `idf.py flash`
- Check the output: `idf.py monitor`
