+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.
+

+* Once-Only Headers

+This directory is intended for project specific (private) libraries.
+PlatformIO will compile them to static libraries and link into executable file.

+The source code of each library should be placed in a an own separate directory

+
+For example, see a structure of the following two libraries `Foo` and `Bar`:

+* The MySensors Arduino library handles the wireless radio link and protocol
+* between your home built sensors/actuators and HA controller of choice.
+* The sensors forms a self healing radio network with optional repeaters. Each
+* repeater and gateway builds a routing tables in EEPROM which keeps track of the
+* network topology allowing messages to be routed to nodes.

+* DESCRIPTION
+* The ArduinoGateway prints data received from sensors on the serial link.
+* The gateway accepts input on serial which will be sent out on radio network.
+*
+* The GW code is designed for Arduino Nano 328p / 16MHz
+*
+* Wire connections (OPTIONAL):
+* - Inclusion button should be connected between digital pin 3 and GND
+* - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
+*
+* LEDs (OPTIONAL):
+* - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
+* - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
+* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
+* - ERR (red) - fast blink on error during transmission error or receive crc error

+This directory is intended for PlatformIO Unit Testing and project tests.
+
+Unit Testing is a software testing method by which individual units of
+source code, sets of one or more MCU program modules together with associated
+control data, usage procedures, and operating procedures, are tested to
+determine whether they are fit for use. Unit testing finds problems early
+in the development cycle.
