Frontier Core (frontier_core) is the base mod for the entirety of the Frontier Mods collection. It contains features, changes, and bug fixes used by most mods of the umbrella.

It is intended as a shared dependency, including for use by other modders. It does nothing by itself; it simply provides the tooling for other mods to do their work without repeating themselves.

Frontier mods which require Core mention it explicitly. If in doubt, verify the mod's dependencies within its modinfo.json.
