 This skill covers everything from identifying the right component for a UI requirement to installing, setting up, and using Ignite UI for React components — including JSX patterns, event handling, refs, controlled/uncontrolled form components, and TypeScript.
 
+## Before You Answer
+
+- Do not guess package names or import paths from memory.
+- First identify the component family, then read the relevant reference files from the Content Guide below.
+- Check `package.json` and keep public or licensed package names consistent.
+- If the required package is not present in `package.json`, add or install the correct Ignite UI dependency first. Absence from `package.json` does not mean the package is invalid.

+### Package Routing
+
+| Component family | Install packages | Import from |
+|---|---|---|
+| Core UI components | `igniteui-react` | `igniteui-react` |
+| Advanced grids | `igniteui-react-grids` (trial) `@infragistics/igniteui-react-grids` (licensed) | `igniteui-react-grids` |
+| Grid Lite | `igniteui-react`, `igniteui-grid-lite` | `igniteui-react`, `igniteui-grid-lite` |
+| Charts | `igniteui-react-charts` (trial) `@infragistics/igniteui-react-charts` (licensed) | `igniteui-react-charts` |
+| Gauges | `igniteui-react-gauges` (trial) `@infragistics/igniteui-react-gauges` (licensed) | `igniteui-react-gauges` |
+| Maps | `igniteui-react-maps` (trial) `@infragistics/igniteui-react-maps` (licensed) | `igniteui-react-maps` |

 ## Best Practices
 
-1. **Start with the MIT package** (`igniteui-react`) — it covers most common UI needs
+1. **Use the package routing table first**
 2. **Import theme CSS first** — components need it to render correctly
 3. **Register chart/gauge/map modules** — call `.register()` at module level
 4. **Wrap charts/gauges/maps in sized containers** — they need explicit dimensions
