What's up?	Where to go
Got a Coral dev board. What do I do?	There's an official Getting Started Guide.
Can't get something working.	The issue tracker is where we talk through problems.
Found something wrong in Google's docs.	Stick it in the issue tracker as a public service.

Overview

Officially, Google Coral is two devices:

Dev Board
A single-board computer with a removable system-on-module (SOM) featuring the Edge TPU.
*    Supported OS: Mendel Linux (derivative of Debian)
*    Supported Framework: TensorFlow Lite
*    Languages: Python (C++ coming soon)

and

USB Accelerator
A USB accessory featuring the Edge TPU that brings ML inferencing to existing systems.
*    Supported OS: Debian Linux
*    Compatible with Raspberry Pi boards
*    Supported Framework: TensorFlow Lite

These devices are brand-spanking new, and as of right now there is very little supporting documentation. This repo exists to help interested devs avoid the twisted hellscape that is Google Product Forums.

OS notes

• Given the observations below (primarily the libc version) the OS appears to be a stock version of Debian 9.0 (Stretch). This knowledge allows us to access Debian sources without much concern.
