I installed SMAPI and got the following: I didn't know what it meant, so I just tried launching the game from the StardewModdingAPI.exe and although it launched, it sent an error message that I had no mods. Can someone please tell me what the SMAPI install message means? What am I supposed to be doing? EDIT: nm, I figured it out. Now how do we delete posts on Nexus? I can't see any option.
