To mint NFTs triggered by Instagram posts:
1. Create an NMKR account for NFT minting on Cardano.
2. Sign up for a Zapier account if you haven't already.
3. Start a new Zap in Zapier.
4. Select Instagram as the trigger app and choose the trigger event (e.g., 'New Media Posted').
5. Connect your Instagram account to Zapier.
6. Set up the NMKR action in Zapier, connecting it to your NMKR account.
7. Configure the NFT minting parameters, using Instagram post data for NFT attributes.
8. Test and activate the Zap.
This will automatically mint an NFT on Cardano each time you post on Instagram.
