-## Beacon Node
+## Creating a new database/testnet
 
-The `$ lighthouse beacon_node` (or `$ lighthouse bn`) command has two primary
-tasks:
+Lighthouse should run out-of-the box and connect to the current testnet
+maintained by Sigma Prime.
 
-- **Resuming** an existing database with `$ lighthouse bn`.
-- **Creating** a new testnet database using `$ lighthouse bn testnet`.

-## Creating a new database

-Use the `$ lighthouse bn testnet` command (see [testnets](./testnets.md) for
-more information).
+However, for developers, testnets can be created by following the instructions
+outlined in [testnets](./testnets.md). The steps listed here will create a
+local database specified to a new testnet.
