1. You first need a wallet. metamask.io is probably the most popular wallet on the market that also offers a browser extension.
2. You need gas for the transactions. You can add gas by going to either your Binance account or trustwallet.com. On both of these two platforms you have the option to buy some Smart Chain BNB coins. Send those BNB coins to your Metamask wallet and you are ready to trade on the Binance Smart Chain.
3. Go to Pancakeswap and click on "Connect" or "Unlock Wallet" at the top right and connect your Metamask Wallet. Follow the instructions and allow PancakeSwap to see your accounts and addresses.
4. At the top, where it now says "Enter an amount", click on "Select a currency" and insert the address of the ZMMD token contract (click to copy address).
5. Press the settings button that you see at the top right corner of the center panel. Adjust slippage to account for the autonomous return and liquidity generation of ZMMD that occurs with each transaction. For more details on slippage, please refer to the table in the section "Slippage".
6. Enter the amount of ZMMD you want to swap and click "Swap". If you have problems, round the number of ZMMD tokens to the nearest 0. Sometimes PancakeSwap has trouble rounding the numbers. Also, leave some BNB so that you don't end up without fuel.
