# sneakernet
|
||||
|
||||
a downloadable archive containing sections of the Memory of the World, an extensive archive of human knowledge which defies copyright in favour of the importance of an open and democratic access to the wealth of human knowledge.
|
||||
|
||||
## usage
|
||||
|
||||
1) plug the usb stick into the cable
|
||||
2) transfer starts & light start to blink
|
||||
3) wait until the light stops blinking
|
||||
3a) press any key until 3)
|
||||
|
||||
_the first file getting copied is packed with all the info you'll need to keep the transfer rolling once you're back home_
