There is a handy MarkDown Tutorial to learn a little more, and if you are visual, and as an artist it's pretty safe to say you are, There are TWO editors I use for my posts. SteemStyle.com and Dillinger.io. I don't connect any other services to them, and I do not put anything into them that may be sensitive (like passwords, etc), but they may prove useful in you new journey.

Best of wishes in 2018!
