Hi Rejjir, and Welcome to Steemit.

Yes, it's best to take a bit of time and get an overview of the Steemit platform. But soon enough, you should start posting, just for the experience and to start learning more about the ins and outs, about what works and what does not work, on this platform.

Below are a few basic points of advice re posting on Steemit.

1. Longer posts are more lucrative than short posts. If you make a post of 20–30 paragraphs, it's more likely to earn rewards.
2. Include some photos, images or graphs, to complement the text.
3. Make sure the text and photos are formatted properly, so that your post looks attractive and appealing.

Hope this helps for now. Good luck, and Full Steem Ahead!
