The AppImage is a stand-alone desktop app. Uncompress the file by double-clicking or entering in a terminal:

cd ~/Downloads # navigate to your download folder
chmod +x ./BitBox-[version]-x86_64.AppImage # make executable
./BitBox-[version]-x86_64.AppImage # to run the app

* If the BitBox device is not detected by the app, you may need to manually adjust USB permissions. To do this for most recent distributions, enter the following line in a terminal (sudo access required), then replug the device:

printf "SUBSYSTEM==\"usb\", TAG+=\"uaccess\", TAG+=\"udev-acl\", SYMLINK+=\"bitbox02_%%n\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"2403\"\n" | sudo tee /etc/udev/rules.d/53-hid-bitbox02.rules > /dev/null && printf "KERNEL==\"hidraw*\", SUBSYSTEM==\"hidraw\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"2403\", TAG+=\"uaccess\", TAG+=\"udev-acl\", SYMLINK+=\"bitbox02_%%n\"\n" | sudo tee /etc/udev/rules.d/54-hid-bitbox02.rules > /dev/null
printf "SUBSYSTEM==\"usb\", TAG+=\"uaccess\", TAG+=\"udev-acl\", SYMLINK+=\"dbb%%n\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"2402\"\n" | sudo tee /etc/udev/rules.d/51-hid-digitalbitbox.rules > /dev/null && printf "KERNEL==\"hidraw*\", SUBSYSTEM==\"hidraw\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"2402\", TAG+=\"uaccess\", TAG+=\"udev-acl\", SYMLINK+=\"dbbf%%n\"\n" | sudo tee /etc/udev/rules.d/52-hid-digitalbitbox.rules > /dev/null

Or, if the above does not work for your distribution, add yourself to the 'plugdev' group (if not already a member; a reboot may be required for some distributions) and enter the following line in a terminal (sudo access required):

printf "SUBSYSTEM==\"usb\", SYMLINK+=\"bitbox02_%%n\", GROUP=\"plugdev\", MODE=\"0664\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"2403\"\n" | sudo tee /etc/udev/rules.d/53-hid-bitbox02.rules > /dev/null && printf "KERNEL==\"hidraw*\", SUBSYSTEM==\"hidraw\", SYMLINK+=\"bitbox02_%%n\", GROUP=\"plugdev\", MODE=\"0664\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"2403\"\n" | sudo tee /etc/udev/rules.d/54-hid-bitbox02.rules > /dev/null
printf "SUBSYSTEM==\"usb\", SYMLINK+=\"dbb%%n\", GROUP=\"plugdev\", MODE=\"0664\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"2402\"\n" | sudo tee /etc/udev/rules.d/51-hid-digitalbitbox.rules > /dev/null && printf "KERNEL==\"hidraw*\", SUBSYSTEM==\"hidraw\", SYMLINK+=\"dbbf%%n\", GROUP=\"plugdev\", MODE=\"0664\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"2402\"\n" | sudo tee /etc/udev/rules.d/52-hid-digitalbitbox.rules > /dev/null
