Adding development Substrate accounts to polkadot.js extension
==============================================================

Accounts like Alice, Bob, Ferdie etc are derived from a pre-known development seed. You can find this here: [https://polkadot.js.org/docs/keyring/start/suri/#dev-accounts](https://polkadot.js.org/docs/keyring/start/suri/#dev-accounts)

So the seed is `bottom drive obey lake curtain smoke basket hold race lonely fit walk`.

Paste `bottom drive obey lake curtain smoke basket hold race lonely fit walk` as the seed, and set a name and password.
