 1. Clone the repository and enter the directory 
-  - `git clone https://development.tornadocash.community/tornadocash/classic-relayer && cd classic-relayer`
+  - `git clone https://git.tornado.ws/tornadocash/classic-relayer -b mainnet-v4 && cd classic-relayer`

+2. Clone the example environment file `.env.example` to configure for the preferred network - `cp .env.example .env` , then fill `.env` file.
-  - By default each network is preconfigured the naming of `.env.<NETWORK SYMBOL>`
-  - `cp .env.example .env.eth` 
   - Set `PRIVATE_KEY` for your relayer address (remove the 0x from your private key)
   - Set `VIRTUAL_HOST` and `LETSENCRYPT_HOST` to your domain address
     - add a A  record DNS record with the value assigned to your instance IP address to configure the domain
   - Set `RELAYER_FEE` to what you would like to charge as your fee (remember 0.3% is deducted from your staked relayer balance)
   - Set `RPC_URL` to a non-censoring RPC endpoint (You can [run your own](https://github.com/feshchenkod/rpc-nodes), or use a [free option](https://chainnodes.org/))
   - Set `ORACLE_RPC_URL` to an Ethereum native RPC endpoint
