How to edit navbar?

[JamesDVN]

Hi,

Since I don't know much about coding, I've searched a lot on the internet to find a solution for adding a new tab to the navbar (Home-Forum-...). I want to place a picture before Home and Forum and it is going to be my home page. Plus, I need to swap the "old" Home with Forum section. Can you please send me a step by step direction so I can overcome this problem without any error.
