-# wifi-printer
+# Wi-Fi Printer
 
-Thermal printer automatically prints addresses and vendors of Wi-Fi devices nearby.
+This project prints all SSIDs, MAC addresses, and their vendors on a thermal printer using a Wi-Fi adaptor in monitor mode.
+
+
+## Overview
+
+
+## Usage
+1. Setup a Raspberry Pi with Raspbian/Raspberry OS
+2. Connect to Internet
+3. Run ``install.sh``-Script
+4. Wait
+5. Set up for further usage, i.e.:
+  * Remove Internet connectivity (not needed anymore)
+  * Connect printer and Wi-Fi adaptor
+  * Include everything into nice device :)
+
+## Important
+* You might need to adapt the printer configuration in ``cms.py`` depending on the printer you use
+* You might need to change the name of the network adaptor in ``install.sh``
