-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
-* Once-Only Headers
-* Computed Includes

-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
-("lib/your_library_name/[here are source files]").
-
-For example, see a structure of the following two libraries `Foo` and `Bar`:
-
-|--lib

-|  |--Foo
-|  |  |- Foo.c
-|  |  |- Foo.h
-|  |
-|  |- README --> THIS FILE
-|
-|- platformio.ini
-|--src
-   |- main.c

-determine whether they are fit for use. Unit testing finds problems early
