-          3) You can now buy UNI test tokens with ETH! Visit the&nbsp;
-          <a href= "https://faucet.rinkeby.io/">Rinkeby faucet</a> to aquire testnet ETH <br/><br/>
-          4) To buy ETH with UNI you must approve the Uniswap smart contract to transfer UNI tokens on your behalf. Click the&nbsp;
-          <span className="instructions-approve"><b>Approve</b></span> button now! (first time only)<br/><br/>
-          5) Rate is variable based on token availiblity, enter number of tokens to see rate and cost.<br/><br/>
-          6) This is a proof-of-concept for a decentralized Market Maker exchange. Stay tuned for ENS support, token-to-token pairs, the ability to become a liquidity provider and collect fees,
-          and a Mainet launch! :) <br/> <br/>
-          7) This demo was hastily programmed by a single developer <i>(Hi, my name is Hayden!)</i>. Please reach out to me with any questions, comments, complaints, or bug reports.<br/><br/>
