Ensure you have ETH in your wallet to convert to $HARRIS. If you don't possess any ETH, you can acquire it directly on Metamask, transfer it from another wallet, or purchase it on a different exchange and send it to your Metamask wallet.
Connect your wallet to UNISWAP. Paste the $HARRIS token address into UNISWAP, select the about of eth that you want to buy, and confirm the transaction. Then, authorize the transaction on Metamask.
