 You can get the type definitions for React Tracking from DefinitelyTyped using `@types/react-tracking`. For an always up-to-date example of syntax, you should consult [the react-tracking type tests](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/react-tracking/test/react-tracking-with-types-tests.tsx).
 
-### PropType Support
-
-The `props.tracking` PropType is exported for use, if desired:
-
-```js
-import { TrackingPropType } from 'react-tracking';
-```
-
-Alternatively, if you want to just silence proptype errors when using [eslint react/prop-types](https://github.com/yannickcr/eslint-plugin-react/blob/master/docs/rules/prop-types.md), you can add this to your eslintrc:
-
-```json
-{
-  "rules": {
-    "react/prop-types": ["error", { "ignore": ["tracking"] }]
-  }
-}
-```
 
 ### Deepmerge
