Welcome to the Steem blockchain, @treasure09.

A good place to go and get started is the Steem-Terminal Discord server. They will gladly answer all the questions you have and guide you around.

To join, all you need to do is create a free Discord account (Discord is the chat-app we Steemians use to talk to each other 'behind the scenes').
You can create your account here: https://discordapp.com

Once you have an account, follow this invitation link to join the @steem-terminal Discord server: https://discord.gg/XZGPGpz
