Attached is an English translation of the main page for LibreQR. Extract the text and install it to /var/www/qr/index.php
LibreQR - index.php.odt (17.1 KB)
I think you should submit this to the project here : https://code.antopie.org/miraty/libreqr
I checked that repository, and it looks like the next version of LibreQR will have an English translation.
