 "Client" isn't exactly the right term, but it's a mesh peer with a user interface. These images can be copied to a USB drive, then you can plug it into a laptop/netbook/desktop machine and boot from it. You will probably also need an Atheros USB wifi dongle (the black protruding object on the left side of the netbook in the picture above), because most built-in wifi usually requires proprietary firmware. In the commands below substitute /dev/sdX with the USB drive device, excluding any trailing numbers (eg. /dev/sdb). The USB drive you're copying to will need to be at least 16GB in size.

 If you're in an emergency and don't have Atheros wifi dongles then there is also an "insecure" image which contains some proprietary wifi drivers which may work with a wider range of laptops. Proprietary drivers *are not recommended* because they're unsupportable and may be exploitable or contain malicious antifeatures which fundamentally compromise the security of the network. However, the trade-off between security/maintainability and simply having the ability to communicate at all may be a valid one in some situations.
