Welcome to steem community @emmanuelboahen.

Besides the whitepaper, I have not really found anything resourceful. You could check this link out for some help: https://steemit.com/steem/@eco-alex/steem-it-for-dummies-a-non-technical-guide.

Steemsavvy.com could become a useful resource if all their training modules have been uploaded, which currently is not.

All the best and Merry Christmas.
