message: Update of the README
diff: This an experimental port of TensorFlow Lite aimed at micro controllers and other devices with only kilobytes of memory. It doesn't require any operating system support, any standard C or C++ libraries, or dynamic memory allocation, so it's designed to be portable even to 'bare metal' systems. The core runtime fits in 16KB on a Cortex M3, and with enough operators to run a speech keyword detection model, takes up a total of 22KB.
  +*Note: not all kernelas are ported yet.*

  The design goals are for the framework to be:
  - **Readable**: We want embedded software engineers to be able to understand what's required to run ML inference without having to study research papers. We've tried to keep the code base small, modular, and have reference implementations of all operations to help with this.
