Make a post about yourself using the hashtag "introduceyourself" then you will get plenty of people offering to help you learn about Steem.
This was my introduceyourself post, as an example: https://steempeak.com/hive-120078/@atma.love/who-am-i
Note: Steem is not Steemit. Steemit is just one of the webpage front ends you can use to post, comment and upvote on the Steem Blockchain. I highly recommend you use steempeak.com instead of steemit.com. steemit.com is now owned by Justin Sun who's criminal actions (co-ercing/bribing exchanges to vote for fake witnesses) to make a hostile takeover of Steem, have caused many issues recently.
