+This demo shows the balance of tokens in your Web3 wallet. 
+If you do not have a Web3 wallet, see instructions on setting up a wallet in the links below.
+Initially, your wallet should have no ETH and OCEAN tokens in it. 
+You can then request ETH and OCEAN test tokens by entering your public address into faucets 
+(follow the links at the bottom of the page). 
+Then wait about 15 seconds and re-run the app for the same private key. 
+This demo uses the Ocean Protocol Python library in the backend. 
+For more information on the advantages of combinining Ocean and HuggingFace, 
+check out the blog post link below.
