# Become a Testnet Validator
[mainnet-validator]: ./mainnet-validator.md
[prater-launchpad]: https://prater.launchpad.ethereum.org/
Joining an Ethereum consensus testnet is a great way to get familiar with staking in Phase 0. All users should
experiment with a testnet prior to staking mainnet ETH.
To join a testnet, you can follow the [Become an Ethereum consensus Mainnet Validator][mainnet-validator]
instructions but with a few differences:
1. Use the appropriate Staking launchpad website:
- [Prater][prater-launchpad]
1. Instead of `--network mainnet`, use the appropriate network flag:
- `--network prater`: Prater.
1. Use a Goerli execution node instead of a mainnet one:
- For Geth, this means using `geth --goerli --http`.
1. Notice that Lighthouse will store its files in a different directory by default:
- `~/.lighthouse/prater`: Prater.

> **Never use real ETH to join a testnet!** All of the testnets listed here use Goerli ETH which is
> basically worthless. This allows experimentation without real-world costs.
