We understand how overwhelming and confusing this could be for a new user. But you will soon find out how useful it would be for you in the future. We would recommend you not to cover every thing quickly. Focus on building your site, bringing visitors, posting content. When you are stuck at something, focus on that specific problem and try to solve it using tutorials on our site or else where.
