Welcome to Steemit, Hive account@catieleta! I find that the guides created by Hive account@adil are the best ones so far:

https://steemit.com/steem/@adil/yes-full-guide-on-steemit-9-0

It includes pretty much everything you will need to know to function on Steemit, make better posts, get better rewards and take more advantage of how the system works, everything is written in a super accessible way (I am also fairly ignorant about crypto, blockchain and all that but his guides are pretty fool-proof). I found them super useful! I hope it helps you too.
