 Follow this instructions to install the Cosmos-SDK and connect to the latest Testnet. This instructions work for both a local machine and a VM in a cloud server.
 
-If you intend to run a non-validator full-node, installing the SDK on a Cloud server is a good option. Although, if you are want to become a validator for the `mainnet` you should look at more complex setups to protect your node from DDOS and ensure high-availability (see the [technical requirements](https://github.com/cosmos/cosmos/blob/master/VALIDATORS_FAQ.md#technical-requirements)).
