# If you boot multiple nodes, make sure each has their own home directory.
mkdir home
```
### Boot
If you do not receive QNS updates in terminal, it's a sign that the default public-access RPC endpoint is rate-limiting or blocking you. Get an eth-sepolia-rpc API key and pass that as an argument. You can get one for free at `alchemy.com`.
Also, make sure not to use the same home directory for two nodes at once! You can use any name for the home directory.
On boot you will be prompted to navigate to `localhost:8080`. Make sure your eth wallet is connected to the Sepolia test network. Login should be very straightforward, just submit the transactions and follow the flow.
