# Testnet (Goerli)

{% hint style="warning" %}
While the Avado machines have a large enough SSD to hold both Mainnet and Testnet Ethereum chains, you will have lower performance if you try to run both chains simultaneously.

If you are already running a Mainnet chain, it is best to [pause those packages](/etherfi/solo-stakers/operation-solo-staker/obol-dvt-explained/avado-setup/additional-configuration.md#remove-or-pause-packages) if you want to use a Testnet chain (e.g. Goerli). If you are running a Mainnet validator, pausing the Mainnet chain will stop that validator from performing its duties!
{% endhint %}

Once you have your Avado machine set up, the next step is to install the Goerli Testnet packages and begin syncing the chain.

### Install Geth and Teku Clients

Navigate to the `DappStore` menu and look for `Goerli Execution Client (geth)` and `Prater Validator + Beacon Chain (Teku)`. These can be found under the `Blockchain Testnets` heading.

The search feature didn't work for me, so you can just use the browsers search function, or look down the list manually 👀
