First you will need an XRP Wallet. We recommend downloading the Xaman App:

Second follow the steps to set up a new wallet or import an existing one. If you are creating a new one, you need to activate the wallet by sending a minimum of 10 XRP.

Third you need to set the Trustline to DAVID. This allows the tokens to be sent to your XRP wallet.

Fourth and finally, connect your Xaman wallet and place a buy order on one of the following Decentralized Exchanges (DEX). The Presale goes live 4/20!
