 We're running an aggregator and validator for our testnet, so you don't have to run any of your own infrastructure. However Arbitrum Rollup is totally decentralized, so if you'd like to run your own infrastructure you can avoid our servers entirely.
 
 The very first step to start building with Arbitrum is [installing](Installation.md). After that you can initialize your local setup by running:
+
 ```bash
-yarn prod:initialize 0x175c0b09453cbb44fb7f56ba5638c43427aa6a85 https://kovan.infura.io/v3/YOUR_INFURA_API_ID

 ```
 
-Running the `prod:initialize` command will create a `arbitrum/rollups/0x175c0b09453cbb44fb7f56ba5638c43427aa6a85` folder with two subfolders, one configured for an aggregator, and the other a validator.

 To deploy the validator and aggregator, run
 
 ```bash
-yarn deploy:validators 0x175c0b09453cbb44fb7f56ba5638c43427aa6a85 --password=[password]
+yarn deploy:validators  0xC34Fd04E698dB75f8381BFA7298e8Ae379bFDA71 --password=[password]
 ```
 
 The password argument is used to secure the validator keystore. On the first deployment you set the password to any value, and on later deployments you must resubmit the same password.
