Manifest

shulker.json declares the Minecraft version, loader, targets, mods, and packs. See the manifest reference.

shulker.lock.json records the exact resolved versions, hashes, and pack commits. See the lock reference.

A target is a build output: a client instance or a server directory.

A pack is another shulker project whose mods and overrides merge into this one.

Mods are resolved from Modrinth or CurseForge.
