+⚠️ **Be cautious when using `dangerouslyUseGlobalCSS`.**
+We provide this option as an escape hatch for quick prototyping.
+Relying on it for code running in production has the following implications:
+- Global CSS is inherently fragile. People use strict methodologies like [BEM](http://getbem.com/introduction/) to workaround the issue.
+- It's harder to keep track of `classes` API changes.
+
+⚠️ When using `dangerouslyUseGlobalCSS` standalone (without Material-UI), you should name your style sheets. `withStyles` has a name option for that:
+```jsx
+const Button = withStyles(styles, { name: 'button' })(ButtonBase)
+```
