 Arduino Lab for MicroPython is a lightweight editor for MicroPython programs, supporting connection with a board, code upload, file transfer and interactive REPL shell.
 This project is sponsored by Arduino, based on original work by [Murilo Polese](http://www.murilopolese.com). This is an experimental pre-release software, please direct any questions only to Github issues.

 ## Technical overview
 
-Arduino Lab for MicroPython is an [Electron](https://www.electronjs.org/) app that has its main purpose to communicate over serial with a microprocessor running [MicroPython](https://micropython.org/). The Electron code is at `/index.js` and inside the folder `/backend`.

-All operations over serial are abstracted and packaged on `micropython.js` which is an attempt of porting `pyboard.py`. The module has its [own repository](https://github.com/arduino/micropython.js) with documentation and examples of usage.
+All operations over serial are abstracted and packaged in `micropython.js` which is a JavaScript implementation of the functionalities provided by `mpremote` (namely `pyboard.py`) from the [MicroPython project](https://github.com/micropython/micropython/tree/master/tools/mpremote/mpremote).

-The User Interface (UI) source code stays inside `/ui` folder and is completely independent of the Electron code.
+The User Interface (UI) source code stays inside `/ui` folder and is completely independent from the Electron code.
 
 The communication between interface and Electron app is accomplished by using the methods and events specified by `/preload.js`.
