+## Generating Keys from the Command Line
+
+The following command will generate a keypair for a given key type:
+
+```shell
+cargo tangle blueprint generate-keys -k <KEY_TYPE> -p <PATH> -s <SURI/SEED> --show-secret
+```
+
+where it is optional to include the path, seed, or the show-secret flags.
+
+
+### Flags
+
+- `-k` or `--key-type`: Required flag. The key type to generate (sr25519, ecdsa, bls_bn254, ed25519, bls381).
+- `-p` or `--path`: The path to write the generated keypair to. If not provided, the keypair will be written solely to stdout.
+- `-s` or `--seed`: The suri/seed to generate the keypair from. If not provided, a random keypair will be generated.
+- `--show-secret`: Denotes that the Private Key should also be printed to stdout. If not provided, only the public key will be printed.
