Is there a tutorial on creating an NFT on TON? thanks in advance for any help

You could also do it using code

Examples in golang:

1. deploy collection - https://github.com/xssnick/tonutils-go/blob/master/example/deploy-nft-collection/main.go
2. mint - https://github.com/xssnick/tonutils-go/blob/master/example/nft-mint/main.go

for basic nft collection just change urls in collection to your website with json attributes.

Ok thanks
