📦 What Kind of Modpacks?

• Your modpack must be a .zip file.
• Inside the ZIP, include all mods you want installed (typically all .jar files for /mods).
• You can include additional folders (e.g., configs), but the installer extracts everything into your Minecraft mods folder, so it's worthless to include those in the zip.
