+How to build PlatformIO based project
+=====================================
+
+1. [Install PlatformIO Core](https://docs.platformio.org/page/core.html)
+2. Download [development platform with examples](https://github.com/platformio/platform-raspberrypi/archive/develop.zip)
+3. Extract ZIP archive
+4. Run these commands:
+
+```shell
+# Change directory to example
+$ cd platform-raspberrypi/examples/arduino-blink
+
+# Build project
+$ pio run
+
+# Upload firmware
+$ pio run --target upload
+
+# Clean build files
+$ pio run --target clean
+```
+
+## Notes
+
+For Raspberry Pi Pico devices, two Arduino cores exist:
+* https://github.com/arduino/ArduinoCore-mbed
+* https://github.com/earlephilhower/arduino-pico
+
+This examples showcases how to use both of these cores in the `platformio.ini`.

+
+This directory is intended for project header files.
+
+A header file is a file containing C declarations and macro definitions
+to be shared between several project source files. You request the use of a
+header file in your project source file (C, C++, etc) located in `src` folder
+by including it, with the C preprocessing directive `#include'.
+
+```src/main.c
+
+#include "header.h"
+
+int main (void)
+{
+ ...
+}
+```
+
+Including a header file produces the same results as copying the header file
+into each source file that needs it. Such copying would be time-consuming
+and error-prone. With a header file, the related declarations appear
+in only one place. If they need to be changed, they can be changed in one
+place, and programs that include the header file will automatically use the
+new version when next recompiled. The header file eliminates the labor of
+finding and changing all the copies as well as the risk that a failure to
+find one copy will result in inconsistencies within a program.
+
+In C, the usual convention is to give header files names that end with `.h'.
+It is most portable to use only letters, digits, dashes, and underscores in
+header file names, and at most one dot.
+
+Read more about using header files in official GCC documentation:
+
+* Include Syntax
+* Include Operation
