-This firmware implements a transparent bridge between Wifi and serial using an ESP8266 module.
+This firmware connects an attached micro-controller to the internet using a ESP8266 Wifi module.
-It also provides support for flash-programming Arduino/AVR microcontrollers as well as
+It implements a number of features:
-LPC800-series and other ARM microcontrollers via the ESP8266.
+- transparent bridge between Wifi and serial, useful for debugging or inputting into a uC
+- flash-programming attached Arduino/AVR microcontrollers as well as LPC800-series and other
