 Introduction
 ************
+
 This firmware powers the `Mois Box`_, based on the `Arduino Yún Shield`_-compatible `Dragino Yun Shield v2.4`_.
 Telemetry data is transmitted to a `custom PHP receiver program <https://github.com/bee-mois/beescale/blob/master/add_line2.php>`_
 over HTTP using the `Yún HTTP Client`_ from the `Bridge Library for Yún devices`_. It is also stored locally on a SD card.
 The most recent firmware version is always available at `node-yun-http.ino`_.

-Build for AVR
-=============
-The build system is based on `Arduino-Makefile`_, a Makefile for Arduino projects.
+The build system is based on `PlatformIO`_, which will install toolchains and build
+your customized firmware without efforts. All you need is a Python installation.

+
+    If you need to build for different targets, or if you want to modernize your dependencies,

-.. note:: You might want to adjust the appropriate Makefile to match your environment.
