Arduino CLI is an all-in-one solution that provides Boards/Library Managers, sketch builder, board detection, uploader,
and many other tools needed to use any Arduino compatible board and platform.

Note: this software is currently under active development: anything can change at any time, API and UI must be
considered unstable until we release version 1.0.0.


For guidance on installation and development, see the User documentation.
