 Finally, start the server with:

 ### Configurations
 
 There are several environment variables to configure the server. You can provide them within the command line, or via `.env` file. An example is given [here](./.env.example).
 
-- `WALLET_PATH=path/to/wallet.json` <br> HollowDB requires an Arweave wallet, specified by this variable. If none is given, it defaults to `./config/wallet.json`.

 - `REDIS_URL=<redis-url>` <br> You need a Redis server running before you start the server, the URL to the server can be provided with a `REDIS_URL` environment variable. The connection URL defaults to `redis://default:redispw@localhost:6379`.
