Connect the wallet that you want to mint your GitPOAPs to.
Depending on how you're eligible (Github activity, Ethereum address, email address), you'll connect either your Github or your email by clicking the blue CONNECT ACCOUNTS button on the top right. If you don't know which you're eligible through, you can check at gitpoap.io/eligibility
If you're eligible to collect a GitPOAP, the CONNECT ACCOUNTS button will turn into a VIEW & MINT button.
Click that and hit "Mint". It'll mint to your connected Ethereum wallet!
You can check to make sure it minted at gitpoap.io/p/[your Ethereum address]
