Try that and see if it works for your version. If so, you will have a SMAPI icon as well as the Stardew icon that you can launch your game from. Launching from the Stardew icon will run vanilla, launching from SMAPI will run modded. (You will NOT see your unmodded farmers from this, at least I didn't).
If that works, you next need to add mods. Which is pretty simple, but try the first part to even see if it's successful.
