-## Inserting Keys to a Node's Keystore

-You can insert fixed keys into a Substrate-based node's keystore with the `insert` command. It is common to use the
-same secret, but with different scheme for substrate key use:

-_Command (Sr25519 - AURA key):_
-```bash
-node key inspect "caution juice atom organ advance problem want pledge someone senior holiday very" --scheme sr25519

-Now you can use the `insert` sub-command to save these keys appropriately for use by your node, all
-we require is the base path, key type, and correct scheme used to do so with a given secret URI:
-
-_Command:_
-```bash
-# Usage
-# node key insert [FLAGS] [OPTIONS] --key-type <key-type>
-
-# Example: Inserting an Aura key (SR25519 Crypto)
-node key insert --suri 0xc8fa03532fb22ee1f7f6908b9c02b4e72483f0dbd66e4cd456b8f34c6230b849 --base-path /tmp/node01 --key-type aura
-
-# Example: Inserting a Grandpa key (ED25519 Crypto)
-node key insert --suri 0xc8fa03532fb22ee1f7f6908b9c02b4e72483f0dbd66e4cd456b8f34c6230b849 --scheme ed25519 --base-path /tmp/node01 --key-type gran
-
-# Example: Inserting a Beefy key (ECDSA Crypto)
-node key insert --suri 0xc8fa03532fb22ee1f7f6908b9c02b4e72483f0dbd66e4cd456b8f34c6230b849 --scheme ecdsa --base-path /tmp/node01 --key-type beefy
