## Starting Keyfork using remote systems
A line of communication should be established with the shardholders, but can be
public and/or insecure. On the system intended to run the Keyfork server, the
public and/or recorded. On the system intended to run the Keyfork server, the
following command can be run:
```sh
keyfork recover remote-shard
```
This command will continuously prompt 33 words followed by a QR code containing
the words, and read in 72 words until all necessary shards are recovered.
The command will continuously prompt a QR code, followed by 33 words, to be
sent to the remote operator. The operator must then perform their operations
and send back their own QR code, optionally followed by 72 words. The QR code
must be scanned by Keyfork, else the 72 words will be required.
Shardholders should run the following command to transport their shards:
### Shard Transport
Upon receiving the QR code and/or the 33 words, Shardholders should run the
following command to transport their shards:
```sh
keyfork shard transport < shards.pgp
```
This command will read in 33 words, prompt for a smartcard PIN, and prompt 72
words, followed by a QR code containing the words.
The QR code must be scanned by Keyfork, else the 33 words will be required.
Once entered, Keyfork will prompt with a new QR code and 72 words. A picture of
the QR code and (if requested by the lead operator) 72 words should be sent
back.
