Andre, welcome to Steemit! I would like to share the following useful resources with you that may help you on your journey.

First stop, Steem.Guide

The Steemit platform supports a variety of content formats:
original blog posts on Steemit, original photos on Steepshot, original videos on DTube, memes on Dmania, live videos on DLive, original open source contribution on utopian.io and original music on DSound to earn STEEM & STEEM backed Dollars.

Perhaps you can learn a little quicker by watching some short videos

Good luck! Patience & persistence are virtues for success on this platform.
