Welcome! Honestly, it's good just to sort of jump in on here and learn as you go. The thing I most suggest and doing enough research (just search within Steemit - lots of good articles) so you understand the passwords and have the owner key kept safe. After that, just post the best content you can and see the magic start to happen :). I'm a singer-songwriter, and Steemit is on the verge of life-changing for me (you can check out my videos if you're interested!).

All the best! xx, Kay
