Download a non-custodial wallet such as Metamask.io and be sure to write down your seed phrase. This is your "master" password.

You can buy Ether on MetaMask via the Wyre or CoinSwitch "buy" button. You can also use an exchange such as Coinbase and send the ETH to your metamask address.

Visit Uniswap to connect your MetaMask wallet & trade your ETH for DINU. You might have to send an "approve" transaction first, then the actual swap. Always leave some ETH in your wallet to cover gas fees.

The contract address is:
0xbb1ee07d6c7baeb702949904080eb61f5d5e7732

You'll get a notification saying your swap was completed and then another one asking if you'd like to import the token information into your wallet. Hit accept and you can now watch your $DINU balance grow!

In case you forget to hit accept, you can always go to "add token" and click "import custom token" and paste the contract address 0xbb1ee07d6c7baeb702949904080eb61f5d5e7732
