+Here's an easy way to create a QR code image you can print out and display so people can quickly join your WiFi network. In Debian, install `qrencode`.
+
+```bash
+apt install qrencode
+```
+
+Once it's installed you can create a QR code as a PNG image.
+
+```bash
+qrencode -s 24 -l H -o "wifi.png" "WIFI:T:WPA;S:<SSID>;P:<Password>;;"
+```
+
+In this example, `-s 24` indicates the image size. `-l H` indicates high error correction, `-o wifi.png` is the output file, and the encoded connection details are last.
+
+For more information, here is the qrencode man page
