Hi there @papi.mati, I see @lovesniper have mentioned us already. It is quite difficult to find any useful posts about how things work on Hive as the content is scattered all over the blockchain. We are slowly building a repository in the account to make it easier for people to find information about Hive. Please feel free to follow us, it will make your life a lot easier!!
You can also check out this post about things newbies should do in their first week. It's based on input from 115 Hive users, so lot of wisdom there!
