 Alternatively, the `solana-install run` command can be used to run the validator
 node while periodically checking for and applying software updates:
 ```bash
-$ solana-install run solana-validator -- --identity ~/validator-keypair.json --voting-keypair ~/validator-vote-keypair.json --ledger ~/validator-config --rpc-port 8899 --entrypoint testnet.solana.com
