Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

Help! I cannot figure out how to share files on Soulseek. I had one file set up at the start (I wish I had known that this would be an immediate requirement or I'd have been better prepared before installing Soulseek) but there's no option for adding new files. Under "Options" --> "File Sharing" there's a box for file sharing but it only gives me the option of REMOVING the shared file, there's no option for adding one, and I removed the only files I had been sharing because I thought maybe it was set up as a one-at-a-time thing so now I'm sharing nothing at all and I'm kind of freaking out.

Please, I want to share files but I'm not a software engineer like pretty much literally everyone else. I'm also very mentally unhealthy so please, I know that it's kind of standard procedure to be a dick on the internet but I can't handle it, I just need help. Please. Please. Please.
