-1. Download or build beacon kit and bera-reth.
-   Ensure your $PATH includes where you installed it.
-2. Review and modify env.sh
+Requires Beacon Kit and Bera-Reth **v1.4.1** or later. Set `CHAIN` to `mainnet` or `bepolia` in `env.sh`.

+1. Install `beacond` and `bera-reth` and ensure both are on your `$PATH`.
+2. Review and modify `env.sh`.
 3. `./fetch-berachain-params.sh`
 4. In one window: `./setup-beacond.sh; ./run-beacond.sh`
 5. In another window: `./setup-reth.sh; ./run-reth.sh`
