 # FilaMan - Filament Management System
 
-A comprehensive filament management system combining ESP32-based hardware for weight measurement and NFC tag reading/writing with a web interface for managing filament spools in conjunction with Bambu Lab AMS and Spoolman.
+FilaMan is a filament management system for 3D printing. It uses ESP32 hardware for weight measurement and NFC tag management. 
+Users can manage filament spools, monitor the status of the Automatic Material System (AMS) and make settings via a web interface. 
+The system integrates seamlessly with [Bambulab](https://bambulab.com/en-us) 3D printers and [Spoolman](https://github.com/Donkie/Spoolman) filament management as well as the [Openspool](https://github.com/spuder/OpenSpool) NFC-TAG format.
 
-## Project Overview
+![Scale](./img/scale_trans.png)
 
-FilaMan is designed to streamline the management of filament spools for 3D printing. The system consists of an ESP32 microcontroller that handles weight measurement and NFC tag operations, and a web interface that allows users to manage filament spools, monitor AMS (Automatic Material System) status, and interact with Spoolman and Bambu Lab printers.
