 ## Initializing the validators
 
+Run the following command to initialize a set of validators for a given Rollup contract. The `contract_path` should be to the same file you submitted to the deployment tool, the `rollup_address` should be the address output by the tool after a successful deployment, and the `eth_url` should be a RPC or WebSocket connection to an Ethereum node.

+You can select to have one or more validators run on your machine for testing purposes.

This folder contains pre-seeded wallets for the created validators. It serves as a lightweight simulation of an enviroment where the validators are running on multiple machines.
