### Using Keyfork: Mounting a Shardfile
This guide assumes an SD card is plugged in with a `shards.pgp` file. The SD
card should be an unmounted card, named something like `mmcblk1p1`, with a
single partition. There may be a similar device with multiple partitions, but
that is the boot drive, and most likely does not contain the shard file. The
shard partition may be mounted using:
```
% lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS

### Using Keyfork: Scanning QR Codes
When running `keyfork recover remote-shard` or `keyfork shard transport`,
Keyfork may prompt for a QR code to be scanned. The QR code can be a screenshot
but should not be skewed (it should show up square on the phone) and should
take up the width of the phone's screen. The phone should be held between two
to three inches from the camera, as holding it further away may lead to a
"light bleeding" effect causing the QR code to become unreadable. The phone
should be held as still as possible to avoid incorporating motion blur.
