# Modding the Cities: Skylines II UI
The game's interface is a web page: React components rendered by Coherent Gameface, shipped on disk as one JavaScript bundle beside one stylesheet.
A UI mod is a second ES module the page loads at startup and hands the module registry, through which it overrides, extends or appends to the game's own components.
Its C# half publishes state and receives calls over the binding layer: every binding is a `group.name` path, pushed, triggered or called across the wire.
Verified against game version 1.6.0f1.
Each reference below states its own baseline.
**IMPORTANT: follow this skill's references on anything they own — or at the very least grep them before acting on a familiar shape, because the frontend diverges from standard web shapes exactly where a prior feels safest, and the guess tends to fail silently.**
## Which source answers what
The installed bundle — `Cities2_Data/Content/Game/UI/index.js`, with `index.css` beside it — is first-party and authoritative for the whole frontend: the module registry and its paths, the component tree, every formatter, the wire format a binding arrives in.
The decompile answers only for the C# half: the binding types in `Colossal.UI.Binding`, and the `Game.UI.*` systems that register them.
The official UI scaffold, which the install carries under `.ModdingToolchain`, answers for the modules a UI mod may import and for the game's TypeScript declarations.
A C# grep that finds nothing about a module, an exp
