+## Basic Usage
+
+### Personal Setup
+
+On an airgapped system, run the following command to generate a BIP-0039
+mnemonic encoding a generated seed:
+
+```sh
+keyfork mnemonic generate
+```
+
+<!--
+The default format is to use system entropy, but playing cards, tarot cards, or
+dice can be used to generate physical entropy
+-->
+
+The Keyfork server can be started by running the following command:
+
+```sh
+keyfork recover mnemonic
+```
+
+### Group Setup
+
+This guide assumes you are sharding to an `N`-of-`M` system with `I` smart
+cards per shardholder. The variables will be used in the following commands as
+`$N`, `$M`, and `$I`. The smart cards will be factory reset during the process.
+
+On an airgapped system, run the following command to generate a file containing
+encrypted shards of a generated seed:
+
+```sh
+keyfork wizard generate-shard-secret --threshold $N --max $M --keys-per-shard $I > shards.pgp
+```
+
+If all shardholders are physically present, the Keyfork server can be started
+by running the following command:
+
+```sh
+keyfork recover shard
+```
+
+Otherwise, the Keyfork server can be started by transporting the shards to the
+machine using the following command:
+
+```sh
+keyfork recover remote-shard
+```
+
+Each shard can be transported by running the following command:
+
+```sh
+keyfork shard transport shard.pgp
+```
+
+### Deriving Keys
+
+Keys can be derived from Keyfork using the `keyfork derive` command, such as
+the following command for an OpenPGP certificate with one of each subkey:
+
+```sh
+keyfork derive openpgp "Ryan Heywood (RyanSquared) <ryan@distrust.co>"
+```
+
 ## Usage
