To mint NFTs triggered by Twitch stream starts:
1. Set up an NMKR account for Cardano NFT minting.
2. Create a Zapier account if needed.
3. Initiate a new Zap in Zapier.
4. Choose Twitch as the trigger app and select the trigger event (e.g., 'Stream Started').
5. Connect your Twitch account to Zapier.
6. Configure the NMKR action in Zapier, linking it to your NMKR account.
7. Set up the NFT minting details, using Twitch stream data for NFT attributes.
8. Test the Zap and activate it.
Now, each time you start a new stream on Twitch, an NFT will be automatically minted through NMKR.
