-The majority of my programming experience is in the following areas (in no particular order):
- - Low level hardware programming
-     - The [NI Re-configurable I/O](https://www.ni.com/en-ca/shop/compactrio.html) based [Athena system](https://www.ni.com/en-us/shop/hardware/products/roborio-advanced-robotics-controller.html?skuId=65909)
-     - The [AVR](https://en.wikipedia.org/wiki/AVR_microcontrollers) based [ATmega32u4](https://www.microchip.com/wwwproducts/en/ATmega32u4)
-     - The [AVR](https://en.wikipedia.org/wiki/AVR_microcontrollers) based [ATmega328p](https://www.microchip.com/wwwproducts/en/ATmega328p)
- - High level scripting
-     - Python
-     - JavaScript
- - Control systems
-     - [Classical control theory](https://en.wikipedia.org/wiki/Classical_control_theory)
-     - [Modern control theory](https://en.wikipedia.org/wiki/Control_theory)
-
-So far on my blog, I have covered each of these areas (and my mis-adventures) *except* AVR programming. Time to change that.

+When writing software for an Arduino, or any other [AVR]()-based device, there are generally three main options. You can use the [Arduino IDE]() with [arduino-cli](), which is in my opinion, a clunky system that is great for high levels of abstraction and teaching people how to program, but lacks any kind of easy customization I am interested in. If you are looking for something more advanced (and works in your favorite IDE), you might look at [PlatformIO](). Finally, you can just program without any Hardware Abstraction Library at all, and use [avr-libc]() along with [avr-gcc]() and [avrdude](). 
+
+This final option is my favorite by far, as it both forces me to think about how the system I am building is actually working "behind the scenes", and lets me do everything exactly the way I want. Unfortunately, when working directly with the AVR system libraries, the only buildsystem / tool that is available (without a lot of extra work) is [Make](). As somebody who spends 90% of his time working with higher-level buildsystems like [Gradle]() and [Bazel](), I don't really like needing to deal with Makefiles, and manually handle dependency loading. This got me thinking. I have spent a lot of time working in Bazel, and cross-compiling for the armv7l platform via the [FRC Toolchain](https://launchpad.net/~wpilib/+archive/ubuntu/toolchain/). How hard can it be to add AVR Toolchain support to Bazel?
+
+*The answer: Its pretty easy.*
