How to shift the graphic arts going to NFT?

Good day to everyone here in the forum, I am not exactly so sure if this is the right thread section to discuss this concern of mine.
 Now, I would like you to know here in the forum that I am a graphic artist and I have a lot of arts painting in my home where of course I am selling it whoever want it. And this a couple of weeks only, I am planning to sell my arts painting here in the cryptocurrency under NFT, but the thing problem is that I don't where to start, due to I don't know how to create my own NFT. I just like to use my arts as my own  NFT? but really don't know where to start? can anyone here give me some sort of advice on this matter, I am gladly willing to listen in your opinion anyway. kindly reply here on the things to do that I must follow,
thanks and have a good day to all.
