I need help. I am not tech-savvy.

I started using Soulseek this week for the first time, and one of the first things it prompts you to do is share some files. Okay, this is reasonable, so I set up a share file but it's really small because A) I did not know I would have to have things already set up before starting an account and B) I do not know how to change things.

Under "Options" -> "File Sharing" there is a box that shows where downloaded stuff goes followed by a box that says "Shared Folders" but there's only an option to remove shared folders, not one to add a new folder.

I do not speak the language of software engineers.

Soulseek has been pretty good for downloading stuff so far but I did get a message from someone saying I should share more stuff and I want to share more stuff I just don't know how.
