 **A standalone Microsoft Teams presence light based on ESP32 and RGB neopixel LEDs.**
 
-Find detailed informations about the project here: [https://toblum.github.io/ESPTeamsPresence/](https://toblum.github.io/ESPTeamsPresence/)
+This project allows you to build a standalone device that visualizes your presence information from Microsoft Teams with colored LEDs. It's easy to build and quite cheap.

+This projects implements the device login flow to authenticate against Microsoft Azure AD and to get a bearer token to call the Graph API to get presence informations for the current user. Everything is implemented in C++ code for Arduino-style microcontrollers and runs directly on the cheap and powerful WiFi-connected ESP32 board. Hardware build and setup is extremely easy and consists only of two active parts and three wires and is powered via Micro-USB. It also features a cool retro-style web UI to configure the widget.
