Hi @edetebenezer,
Although there are few typos, technically you have very well presented tutorial, all codes are well-explained one by one for each roadmap of this tutorial. Screenshots are neat and well-presented too. One thing that I noticed is about the annotations Getter and Setter. I suggest having it like this one @Getter and @Setter. The Steemit website is very responsive and when using @ it refers that one to a link of a Steemit username. This also applies to @Required and @PrimaryKey annotations. Overall, those are just cosmetics, and the tutorial is well-taught.
