Connect the Temple wallet extension to your Chrome or Firefox browser. Please follow the instructions explicitly. Because once it is connected to the DAPP it is basically done. It is short and easy.
Purchase Tezos if you have not already, and transfer it to your new Temple wallet.
Enter the Guild program through our DAPP, accessing the DAPP from your browser that already should have the Temple wallet extension on the browser. You may enter with as little as $25 worth of Tezos.
