How to get DCBurger's Portraits to Work with 1.6
(With pictures)
Go to DCBUrger's Portait mod on the nexus and download the 1.5.1 version.
Go to the nexus and download the alpha version of portraiture.
Go to your file explorer and unzip those downloads with something like 7zip. I unzip all my mods into a master folder and the copy and paste them wherever from there. It'll look like this unzipped. (highlighted ones)
Click into portraiture once and copy and paste that folder (it'll just say portraiture) into your mods folder for stardew valley.
Then click into the DCburger TWICE (there should be a READ ME under the file you are going to copy) and copy that folder into portraiture like this.
Your file folder should look exactly like this. The portraits should be inside that highlighted folder shown.
