To use coolbot, go to your wallet and click on your steem dollars balance, there will be a drop down and you should click on "Transfer". Then in the "To" box, type coolbot. For the amount, you can do as little as 0.001 or as much as 0.01. Then in the memo you need to put the link to your post that you want coolbot to vote on, and then press the Send button.


I hope that helps you!
