Install SMAPI first. That’s the mod loader that makes everything work. Use Vortex or manual installs for mods. Nexus Mods is the main source.
Stardew Expanded is a must-have. Makes the game feel brand new.
Always back up your saves before going mod-crazy. Trust.
Update SMAPI and all your mods after every patch. Avoids crashes.
Check compatibility before stacking 20+ mods. Stuff breaks fast.
Content Patcher and Json Assets are key for most custom mods.
Read mod descriptions! Some need configs to work right.
