Basics
You can earn money in alot of different ways using steemit. The best way is by posting. This can be any form of content. Writing articles seems to be the best way in my opinion. How much money you make depends on different things. For example, if the person who upvoted your post has alot of the SP (= steam power), then you will earn more money then if a low SP user upvotes your post.
Other ways
You can also earn quite a bit of money commenting. Yes, even leaving comments can make you money. These comments can be upvoted by other users. It can be a good idea to join steemit groups/communities. You can find these groups/communities on almost every social media platform.
