Step 2: After clicking on "Presale" you can set the number of NFTs to reflect the quantity of your drop. You can also set the price-per-mint, which will apply to all your NFT's.
Next, set the max number of NFT's that any one wallet can mint in the "Max NFTs Per Wallet" section. The "Max NFTs Per Mint" section allows people to mint your NFTs in batches, but will not exceed the Max NFTs Per Wallet limit.
