Make sure you have MAMA-DAI LP tokens in your wallet. You need to go to QuickSwap and add liquidity for the MAMA-DAI LP pool to acquire them. Find the link to provide liquidity to the pool here.
Head to the MAMA-DAI LP Bond page of the MAMA DAO webapp here. There are two tabs: "Bond" and "Redeem". Make sure "Bond" is selected.
Type in the amount of MAMA-DAI LP tokens you would like to use in order to mint MAMA. Make sure you are not trying to mint more than it's allowed. The Max You Can Buy field below shows the maximum amount of MAMA you can purchase.
If this is your first purchase, you need to approve the MAMA DAO contract to spend your MAMA-DAI LP tokens. Click "Approve" and sign the transaction.
After the "Approve" transaction has been processed successfully, refresh the page. The "Approve" button should be changed to display "Bond" by now.
Click "Bond" and sign the transaction. There you go, you have minted MAMA using MAMA-DAI LP tokens!
